# How to build a rooming list for a group Source: https://www.roamlytravel.com/guides/rooming-list-how-to Publisher: Roamly Travel Last reviewed: 2026-10-30 Audience: Event organisers, Corporate groups, Universities, Schools, Sports teams ## Short answer A rooming list is the document that tells a hotel who is staying, in which room type, on which nights. Build it from a single master spreadsheet, collect names exactly as they appear on ID, and send it by the deadline in the hotel contract, with each later change issued as a new dated version. Collect only the personal data you need, because some countries require hotels to register guests' identity details with the authorities and UK GDPR limits what you should gather. ## Key takeaways - A rooming list names every guest, with room type, sharers, arrival and departure dates and billing instructions. The hotel contract sets the deadline and the format. - Keep one master list and send the hotel numbered, dated versions. Never send a list of edits, and ask for written confirmation of each version. - Use names exactly as they appear on the guest's ID. Spain's Royal Decree 933/2021 requires hotels to record name, ID document, nationality, date of birth and residence for every traveller. - UK GDPR requires personal data to be limited to what is necessary, so ask for passport or date of birth details only when the hotel or country requires them. - Dietary and access information is special category data. Share it with a hotel only in the form and at the stage it needs to act on it. - Reconcile the final list against the hotel's records and invoice, so you pay for the rooms used and no more. ## What is a rooming list and when do you need one? A rooming list is a roster of guests that an organiser gives a hotel so it can allocate rooms. You need one when you book rooms centrally, for example for speakers, staff, sports squads, student groups or incentive winners. If delegates book their own rooms against a block, the hotel builds the list from their reservations and you track pickup instead. Brown University's hotel guidance describes these two reservation methods: a rooming list supplied by the organiser, or individual bookings by guests. The hotel contract usually sets the deadline, format and required fields. Our guide to [hotel room block contract terms](https://www.roamlytravel.com/guides/hotel-room-block-contract-terms) covers how that deadline relates to the cut-off date and attrition. ## What should a rooming list contain? Start with the fields the contract asks for, then add the ones you need to run the stay. Keep the master list in one place and treat it as the single source of truth. *Typical rooming list fields* | Field | Why it is needed | Notes | | --- | --- | --- | | Full name | Hotel registration and key cards. | Use the spelling on the guest's ID, not a nickname. | | Room type and sharer | Allocates twin, double or single rooms. | For twin rooms, name both guests on the same line or give a shared reference. | | Arrival and departure dates | Sets the nights charged. | Confirm late arrivals and early departures separately. | | Billing instruction | Decides what goes to the master account. | State what you pay (room, breakfast, taxes) and what guests pay themselves. | | Special requests | Lets the hotel act in advance. | Accessible room, early check-in, adjoining rooms. | | Contact for the guest | Hotel can reach them about changes. | Only if the hotel needs it. Avoid sharing more than necessary. | Do not add fields because they might be useful. Every extra column is personal data you must protect and later delete. ## How do you collect the details without chasing everyone? 1. Send one short form to every guest, with a deadline several days before the hotel's deadline so you have time to chase. 2. Ask for the name as shown on ID, dates of stay, sharing preference and any adjustment they need for the room. Ask only what you will use. 3. Check the responses against your booking records for duplicates, spelling and date clashes before you build the list. 4. Keep a log of changes with the date, who asked and what was agreed. ## What identity data do hotels need, and what can you collect? Some countries require hotels to register guests' identity details with the state. Spain is one example. Royal Decree 933/2021 requires accommodation providers to record, for each traveller, their name, sex, ID document type and number, nationality, date of birth, habitual residence and contact details. It also requires the data to be sent to the authorities, immediately and in all cases within 24 hours of the reservation or the start of the service, and to be kept for three years. For under-14s, the adult travelling with them supplies the data. That obligation falls on the hotel, but it affects you because the hotel may ask your group for those details in advance. If so, ask the hotel exactly which fields it needs and collect those only from the guests who will stay there. In the UK, the ICO's guidance says personal data must be adequate, relevant and limited to what is necessary, and that you should not collect data speculatively. The Spanish data protection authority has also said that, in general, a form with the required data is enough and photocopies of identity documents are not needed. Always check with the hotel what its country requires, because rules differ. > **Special category data** > Dietary needs, mobility needs and similar details can reveal health conditions or religious belief, which UK GDPR treats as special category data. Share them with the hotel in the form it needs to act, such as 'accessible room' or 'allergen-free breakfast', and not as a blanket spreadsheet column that every supplier sees. ## How should you send changes and keep the list accurate? - Send the first list by the contract deadline, labelled version 1 with the date. - Issue every later change as a new complete version, never as a list of edits, so the hotel always works from one document. - Ask the hotel to confirm each version by email, and keep its confirmation with the contract. - Check what the contract says about changes after the cut-off date, including name changes and late cancellations, and whether the hotel charges for them. - Compare your list with the hotel's own record a few days before arrival, so errors are found before the front desk queue forms. Where a guest cancels, state whether the room is released or reassigned to someone else, and note who is responsible for the charge if it cannot be resold. ## How do you reconcile the rooming list afterwards? When the event ends, compare the hotel's night-by-night record with your final list. Check that room nights match, that any attrition calculation uses the same numbers, and that personal charges went to guests and not to your master account. Our [conference delegate travel guide](https://www.roamlytravel.com/guides/conference-delegate-travel) sets out the full reconciliation process. Then delete or anonymise the guest details you no longer need, in line with your retention policy. ## How Roamly can help Roamly's [event management](https://www.roamlytravel.com/services/event-management) and [logistics](https://www.roamlytravel.com/services/logistics) services cover rooming lists, hotel liaison and arrival planning for events and group trips.

A rooming list is the organiser's roster of named guests sent to the hotel, usually with room types and dates. A reservation list is what the hotel holds once bookings are made. They should match, and you should compare them before arrival. ### When is the rooming list due? The hotel contract sets the date, usually before the cut-off date. Check the exact deadline and format in your contract, because hotels differ. ### Do I need guests' passport numbers for a rooming list? Not always. Ask the hotel what it needs. Some countries, such as Spain, require hotels to record the ID document number of every guest, but that is the hotel's obligation, and you should collect the data only if the hotel asks for it in advance. ### How should I list guests who share a room? Name both guests, give them the same room reference, and state the bed type. Agree in advance what happens if one of them cancels. ### How long should I keep rooming list data? Keep it only as long as you need it for the event and the reconciliation, then delete it according to a retention period you set in advance. UK GDPR does not allow you to keep personal data longer than necessary. ## Sources - [BOE: Real Decreto 933/2021, registro documental e informacion de viajeros (hospedaje)](https://www.boe.es/diario_boe/txt.php?id=BOE-A-2021-17461) - [Spanish data protection authority (AEPD): note on the accommodation register](https://www.aepd.es/guias/nota-aepd-registro-hospedajes.pdf) - [ICO: Principle (c), data minimisation](https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/data-protection-principles/a-guide-to-the-data-protection-principles/data-minimisation/) - [ICO: What is special category data?](https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/lawful-basis/special-category-data/what-is-special-category-data/) - [Brown University: Hotel room block agreements, guidelines for departments](https://procurement.brown.edu/sites/default/files/documents/Hotel-Room-Block-Agreements-Guidelines-for-Brown-Departments-10-02-23.pdf)
