Revenue at a thermal hotel: rooms, pool entry and cure packages priced together

A thermal hotel prices three products on one shared capacity: the room, the day entry to the water, and the multi-night cure package. Price them together by measuring revenue per guest and per available pool or treatment hour, not per room alone, and cap day entries on dates the water is already full. That is thermal hotel revenue management in one sentence.

On a Saturday in February the pool is full, the car park is full and the restaurant is turning people away, while rooms upstairs are still unsold. The revenue that day came from three different customers who never appear on the same report. After reading this article you will be able to separate those three customers, find the resource that actually runs out first, price the day entry and the cure package from their parts, and read a monthly report that shows all three lines.

Who are the three customers a thermal hotel sells to?#

A thermal hotel sells to stay guests, cure guests and day guests, and they buy different things at different times from the same water.

The stay guest buys a room, usually with board, and treats the pool as an amenity included in the room rate. The unit of sale is the night and the room type. The cure guest buys a series of sessions across several nights; the unit of sale is the session count and the program length, and the room is the accommodation that makes the series possible. The day guest buys a few hours in the water, sometimes with a treatment or a meal, and no night at all. The unit of sale is the entry, and the cost to serve is towels, locker, cleaning and staff attention at the busiest hours.

The regulation draws a useful line here. The Ministry of Health's Kaplıcalar Yönetmeliği separates a cure (kür), a treatment method given in set doses, in series and at regular intervals, from recreation, the use of natural therapeutic elements for tourism and rest rather than treatment (Mevzuat Bilgi Sistemi, T.C. Sağlık Bakanlığı, Kaplıcalar Yönetmeliği consolidated text, Article 4, 7 November 2026 (opens in a new tab)). A recreation guest and a cure guest are not buying the same thing, so they should not carry the same price logic.

Each type has a different booking curve, a different cost to serve and a different sensitivity to price, so a single average rate hides all three. Define the three in the property's own words before pricing anything: if the front desk counts a day guest as a visitor and the sales office counts them as a customer, no report will ever reconcile. Then decide which type owns each hour of the day. Without that decision, the loudest customer at the desk sets the price.

What actually limits a thermal hotel's revenue?#

The limit is usually the pool, the changing rooms and the treatment rooms at particular hours, plus restaurant seats, not the number of rooms.

Build a capacity sheet per hour, not per day: how many people may be in the water at once, how many treatment rooms are staffed, how many covers the restaurant can serve at 19:00, how many lockers the changing rooms hold. The water itself sets a ceiling through flow rate, cooling and storage. The water and hygiene side is set by the facility's own operating and hygiene rules and by the health legislation that applies to it; confirm your case with your legal adviser.

Treatment capacity is a staffing decision. Spa and thalassotherapy facilities must employ a specialist physician and health staff with at least high-school-level health training (Mevzuat Bilgi Sistemi, T.C. Sağlık Bakanlığı, Kaplıcalar Yönetmeliği consolidated text, Article 14, 7 November 2026). The number of sessions you can sell is therefore fixed by the roster before it is fixed by demand.

Peak hours collide. The day guest's peak runs from late morning to late afternoon, the stay guest wants the pool in the afternoon, and the cure guest's session times are set by the program rather than by demand. An unsold room is lost capacity for one night; an unsold pool hour is lost forever. The scarce units are the bather-hour and the treatment-hour.

Run the check on your best day last month: which resource ran out first, the water, the treatment rooms, the restaurant or the car park? If nobody can answer, the constraint is still unknown and every price is a guess.

How should you price a day entry to the pool?#

Price day entry against the room rate it competes with, cap it by date rather than by season, and keep it out of the hours the cure program needs.

Set the floor at the marginal cost of hosting a day guest: towel, locker, cleaning, water treatment, staff attention and the share of the changing room. The ceiling is the value of that pool hour to a stay guest who is already paying for the room. Split the product by time band: a morning entry, an afternoon entry and a full day cost you different amounts of capacity and should not carry the same price.

Cap by date, not by season. Publish a daily cap on entries and close sales when it is reached; the cap protects the stay guest's experience, which is what the room rate is actually paying for. On dates when rooms are selling well, raise the day price or close the day product. A day guest who displaces a room guest is a loss even at a high entry price.

Treat day entry as an upgrade path. A day guest who adds a treatment or a meal is worth more than the entry fee, and a day guest who later books a night is the cheapest acquisition the hotel has. Publish the terms in plain words: arrival window, what is included, what happens when the cap is reached, and the refund rules. Day guests compare you on the phone with three other facilities in ten minutes. Check the consumer-law side of your cancellation and no-show terms with your legal adviser before printing them. The same logic applies to selling daytime room use, covered in day-use rooms and pricing daytime stays without hurting the night's sale.

How do you build a multi-night cure package from its parts?#

Build the package from priced parts, nights, board, a set number of sessions, the session type and water access, so the package price is a sum you can defend and re-cut.

List the parts first: nights, board type, session count, session type, water access, and any transfer. Each part has its own cost and its own stand-alone market price. Choose the session count before the nights: a cure is given in series at regular intervals (Mevzuat Bilgi Sistemi, T.C. Sağlık Bakanlığı, Kaplıcalar Yönetmeliği consolidated text, Article 4, 7 November 2026), so the program length drives the stay length, not the other way round.

Price the package as the sum of its parts minus a stated package discount, and print the discount as a number. The sales team can then explain it and finance can reverse it. Keep every part sellable alone: a guest who wants three nights and four sessions must be quotable without anyone inventing a new package at the desk.

The regulation defines a cure and a spa treatment but does not define a cure package and does not regulate what a facility may call one. What it does regulate is the facility permit and operating permit from the governorship (Article 17), the staffing (Article 14) and, for health services offered for treatment according to the water's indication, a separate Ministry of Health permission (Article 22). Confirm your own scope with the Ministry and your legal adviser before you print anything that reads as a health promise. In the description, state what is included, how many sessions, over how many days and who delivers them. Never describe an outcome.

A final check: can the reservations team rebuild the package price by hand in under a minute? If not, the package carries too many rules to sell on the phone. The general mechanics of bundling a room with extras are covered in pricing a room with spa, dinner or transfer as one package offer.

How do weekday, weekend and school-break patterns differ?#

A thermal hotel runs two demand curves at once, midweek cure and long-stay demand and weekend family and day-guest demand, and the two need separate prices and separate caps.

Midweek belongs to cure guests and longer stays: booked further ahead, more price-sensitive, low day-entry demand. The constraint is treatment capacity and restaurant covers, not the pool. The weekend belongs to families and day guests: shorter lead time, higher tolerance for the day price, and the pool and changing rooms become the constraint. School breaks and public holidays push family demand and day demand onto the same dates, where the day cap and the pool-hour schedule do work that no rate change can do.

Keep one calendar with the three demand types marked on it, so the day cap, the package release dates and the minimum-stay rules all follow the same sheet; the approach is described in building a hotel demand calendar of holidays, school breaks and events on one sheet. Do not apply one minimum-stay rule all year: a two-night minimum protects a weekend and damages a midweek cure stay that was going to be five nights anyway. Watch the shoulder weeks between a holiday and a normal week; that is where the day cap can be relaxed and the cure package pushed at the same time.

What should a thermal hotel's monthly report show?#

Report revenue per available room next to revenue per guest, per available treatment hour and per bather-hour, because a room-only report cannot see two of the three customers.

Revenue per available room (RevPAR) is room revenue divided by available rooms. It is necessary and it is blind to day guests and to treatments sold to people who are not staying. Total revenue per available room (TRevPAR) adds food, beverage, treatments and day entries to the numerator; it is the smallest change that makes all three lines visible on one page, and it is explained in TRevPAR explained, and what to count in it. Add revenue per guest, total revenue divided by the number of people served whether or not they stayed, and revenue per available treatment hour. Put the day guest into the denominator of something, or the day business will always look like free money while it quietly consumes the pool.

Split the report by customer type, not only by department. The same restaurant revenue means something different from a cure guest and from a day guest. Do not compare your own occupancy figure with the Ministry's published one without knowing its definition: the Ministry publishes an occupancy rate for certified facilities, and the definition of that column is not stated in the published file (Ministry of Culture and Tourism, certified accommodation statistics, August 2026). Read the day cap and the package release in the same monthly review, so capacity decisions and pricing decisions are looked at together rather than in separate meetings.

What to do next#

Take one peak day and one ordinary midweek day from last month and fill in the capacity sheet for each: bathers per hour, staffed treatment rooms, covers, lockers. Whichever resource ran out first is your real constraint, and every price in this article follows from it. Once the constraint is written down, the day cap, the package parts and the monthly report stop being three separate arguments and become one pricing decision.
