Can my customers add a special request like a late check in or a quiet room when they book a hotel on my website?

Yes, in most cases you can collect a special request at the time of booking and have it travel with the reservation to the hotel. On a hotel booking page this usually appears as a short notes box on the guest details step, and whatever your customer types there is sent to the supplier along with the booking, so it reaches the property with the rest of the reservation details.

The important thing to be honest about is that a special request is only ever a request. The hotel decides at check in whether it can give a quiet room, a high floor, twin beds, adjoining rooms or a late arrival. Sending the note does not reserve anything and it does not change the room type your customer paid for. If a customer genuinely needs a specific room type or bed setup, it is safer to book a rate that already includes it than to rely on a note.

How much you can send also depends on the supplier behind that particular hotel. Some accept free text and pass it straight through, some only accept a fixed list of common requests, and a few ignore notes completely on certain rates. Anything that carries a charge, such as an extra bed, early check in or late check out, normally has to be arranged and paid directly at the property rather than through the request box.

It is worth doing a test booking with the supplier you use most and seeing whether your request text shows up on the voucher, then wording the box on your site so customers know requests are subject to availability at the hotel.
