If my customer wants to add an extra night to a hotel booking they have already paid for, can I change the booking or do I have to cancel and book it again?

In most cases you will have to cancel and book again, because very few hotel suppliers let a confirmed booking be changed after it is issued. The hotel booking API will pass on an amendment request where the supplier actually supports one, but what can be amended is usually limited to small things like correcting the spelling of a guest name or adding a note for the hotel. Changing the dates, the number of nights or the number of rooms is normally treated as a brand new booking.

So the practical route is to look at the cancellation policy on the existing booking first. If the free cancellation deadline has not passed, you can cancel the original booking and make a new one covering the longer stay. The thing to be careful about is that you are not guaranteed the same room at the same rate when you rebook, because availability and rates move all the time. It is safer to check what the new stay would cost and whether the room is still available before you cancel anything, not after.

If the booking is non refundable, cancelling will usually mean losing the money, so in that situation it is worth asking us to put a request to the supplier or the hotel directly. Some hotels will extend a stay as a goodwill gesture, often by charging the extra night separately at the rate they have on the day. That is entirely the hotel's decision and we cannot promise it will be agreed.

Before you do anything, open the booking in the software and check the cancellation deadline and the live price for the new dates, then come back to us with the booking reference if the rate is non refundable and you need us to ask the hotel.
