Hello, I booked a hotel room on Ctrip. 2 1 this month. Will the hotel not approve my reservation because the room is tight?

Usually not. You can call the hotel yourself and ask if you have reserved a room. Moreover, if you can't arrive at the booking time on 2 1, you should call Ctrip or the hotel in time, because Ctrip won't leave your phone number when booking the hotel, so if the booking time is up, but you don't arrive at the store, they will directly cancel it for you. The price will not change. If so, you can call Ctrip and they will coordinate with you, or you can complain directly to the hotel. As long as it is a regular hotel, the price will not be changed casually.
