I want to travel to Sanya during the Spring Festival. How long in advance is it cheaper to book a hotel? Book on the app

I personally think that booking a room on the app is better than booking directly on the hotel’s official website. Of course you have to book in advance, there are discounts a month or 14 days in advance. After all, booking on the APP is through a third-party platform, which is very inconvenient because of this and that. And it’s not convenient to cancel. The last time I canceled, the third-party platform and the hotel pushed back and forth. I recommend going directly to the hotel’s official website to book. I made a reservation on the official website of Yalong Bay Guesthouse before, and the service was particularly good.
