Can I get a refund if I have no time to buy a hotel room in Ctrip?

This also depends on the situation. You should read carefully whether it says unsubscribe below. If you write it, there is also a time limit, such as how long in advance you can get a full refund, how long you can get a proportional refund, and how long you don't return it. There are also special rooms and activities, which are generally not returned.
