Can I book a two-night package on Ctrip instead of two nights? Hotel Atlantis

First, check the booking rules of Ctrip. If you can cancel at any time in advance, then cancel and reschedule.

If you can't negotiate with the hotel, if the price of one room for two nights is the same as that of two rooms for one night, the hotel can help you change it if you are not satisfied with the reservation, but if the hotel's reservation for that day is full, there may be no way out!
