Ctrip has successfully booked a hotel, so will there be a room when I go?

As long as the reservation is successful and you arrive at the hotel before the appointed time, you should have a room and you don't need to pay a few days in advance.

If there is no room at that time, Ctrip will pay the fee. Unless you make a mistake, or arrange your room for someone else, or the hotel sells the house at a high price, the room is still guaranteed.

I hope it helps you.
