Bringing a delegation, a school party or a wedding crowd to Istanbul or Antalya? Group hotel booking in Türkiye follows the same logic as anywhere else, with a few local details on tax and invoicing. Once you need around ten rooms, the hotel stops treating them as separate reservations. It sets up a room block under one contract, and that contract runs to a calendar: how long rooms are held, when names are due, and when unused rooms go back on sale.
How a group booking differs
The hotel decides what counts as a group. At the large chains the threshold is usually ten rooms. Marriott lets planners book blocks of 10 to 25 rooms on its website, and Hilton confirms up to 25 rooms online. Both ask for a proposal request above that (both pages read on 12 November 2026). Independent hotels may set a different threshold, so ask.
An individual booking stands alone, with its own rate and cancellation rule. A group booking puts every room under a single agreement, and that agreement fixes the dates as well as the price:
| Stage | What happens | What the hotel needs from you |
|---|---|---|
| Quote | The hotel sets out rates, room types and terms | Dates, nights, room mix |
| Option | Rooms are held until you confirm | Confirmation before the option date |
| Contract and deposit | The block is confirmed and the payment schedule starts | Signature and first payment |
| Rooming list | Names and room allocation go to the hotel | The list by the contract deadline |
| Cut-off date | Unused rooms return to general sale | Your final room count |
| Arrival | The group checks in | Arrival times in advance |
What to send the hotel
A request with gaps comes back late or changes later. Have these ready before you ask for a quote:
- Arrival and departure dates, plus any flexibility
- Number of nights, and anyone arriving early or leaving late
- Room mix: singles, doubles, family rooms
- Board basis, such as bed and breakfast or half board
- Budget range per person or per room
- Special requests: rooms on the same floor, accessible rooms, connecting rooms
- How long your internal approval takes
The last point is the one people forget. If sign-off takes a week, the option has to last at least that long. Say so at the quote stage rather than losing the rooms when the option lapses.
Options and the cut-off date
These two dates are easy to confuse. The option date is the last day the hotel holds rooms for a group that has not yet confirmed. The Events Industry Council glossary defines it as a prearranged date after which the hotel no longer holds tentative arrangements. Miss it without confirming or paying a deposit, and the rooms can go to other guests.
The cut-off date, also called the release date, comes after the contract is signed. In the same glossary it is the date the hotel releases unsold rooms in the block to the general public. After that, adding rooms depends on how full the hotel is, and the group rate is no longer guaranteed. If a few people might join late, keep their rooms in the block until cut-off.
When the block shrinks: attrition
Most group contracts include an attrition clause. It covers the gap between the room nights you contracted and the room nights you actually use. Contracts often allow a set shortfall, which the glossary calls slippage, and the hotel charges for every room night beyond it.
The allowance and the dates it applies to vary between hotels. Before signing, check how many room nights the allowance comes to, how the charge is calculated, and whether the allowance changes after the cut-off date. If your numbers are uncertain, ask about opening a smaller block and adding rooms later.
Rooming lists and flight deadlines
A rooming list is the single document that delivers several reservations to the hotel at once. Each line gives the guest's name, room type, who they share with, and their arrival and departure dates. The deadline is in the contract and often sits close to the cut-off date.
If the group flies in, the hotel list and the flight list run on separate deadlines. Turkish Airlines expects a group's name list 30 days before the flight, while Pegasus needs every name before the fare option expires. Our guide to group flights with Turkish Airlines and Pegasus has the details. When you copy names across, match them to the spelling in each passport. A mismatch slows things down at reception.
For a group landing in the morning, ask about check-in time. If rooms will not be ready, request early check-in or luggage storage. If everyone travels from the airport in one vehicle, the transfer has to fit the flight times, and we can plan the airport transfer together with the hotel block.
Payment, cancellation and invoices
Deposit size, the final payment date and the cancellation scale all depend on the contract. Cancellation charges usually rise as arrival gets closer. Ask for each step with its date and amount, rather than a vague line such as "late cancellations may be charged".
In Türkiye an accommodation tax is added to the room price on top of VAT. It applies whatever the guest's nationality, and the rate can be changed by presidential decree. Ask in writing whether quoted rates include taxes, and which currency the invoice will be issued in. Hotels abroad may also add a city tax.
Decide early whether you want one invoice in your organisation's name or separate invoices per guest. If some guests will pay their own extras, the contract should say so.
When another team is the right fit
If the group also needs a meeting room, staging and a programme, our group company Seda Mice organises the event itself. Its meetings page explains how. Football teams on training camps are covered by our group's team accommodation service. And if your company sends staff to the same cities all year, a corporate hotel agreement may suit you better than a one-off block.

Frequently asked questions
How many rooms count as a group?
It depends on the hotel. The large chains usually start at ten rooms, and independent hotels may use a different number.
Is a group rate cheaper than booking rooms individually?
Not always. The rate depends on the dates and how full the hotel is. The real gain is one rate and one set of terms for every room. Compare the group rate with the individual rate on the same day.
Can we reduce the number of rooms later?
Yes, if the contract has a shortfall allowance, and only within it. Room nights beyond the allowance are charged under the attrition clause.
Can we change names?
Until the rooming list goes to the hotel, the names are yours to change. After that, changes depend on the hotel's rules, so ask how they work when you negotiate the contract.
Can we add rooms after the cut-off date?
Only if the hotel still has rooms. The group rate may not apply, and the hotel can charge the rate of the day.
Can we get one invoice for the whole group?
Yes. Ask for a single invoice in your organisation's name at the quote stage, and have the contract state how personal extras are handled.
