Can I use it again on the day of successful hotel reservation?

I don't know what kind of appointment you are talking about. What about a reservation with a deposit? Or is it just a verbal agreement? Hotels usually keep reservations for half an hour at most, and then they will be used by tourists. If you can't book a room, you'll be fine without paying the deposit. If you pay the deposit, you must discuss it with the hotel. Because if you don't check in, the room is reserved for you and can't be sold any more, which will waste the resources of the hotel. So I will ask you to pay a certain amount many times. Of course, this is not a rule, it depends on the specific hotel. Not exactly.
