Can a hotel booking API send a guest's bed preference or arrival time to the hotel?

Yes, a hotel booking API can often send guest requests such as a preferred bed type, an expected arrival time, an accessible room request or a preference for a quiet room. The exact choices depend on what the hotel supplier accepts and what information the hotel provides for that booking.

These details are normally treated as requests, not confirmed services. A hotel may receive the request but still be unable to provide it because of room availability, hotel policy or operational limits. The booking page should make this clear so the customer does not assume that a preferred bed or room location is guaranteed.

Some suppliers provide separate fields for common requests, while others accept only a general note or do not accept extra requests at all. A request may also need to be added after the reservation is confirmed. For important needs, such as accessibility or arrival outside the usual check in period, the traveller should receive clear confirmation from the hotel before relying on the arrangement.

Ask glideFares which guest request fields are supported by your chosen hotel supply, then test how those requests appear in the booking confirmation and check whether the hotel must confirm them separately.
