What should I do if Kempinski Hotel Sanya Haitang Bay checks out late?

Generally, late check-out will be charged for half a day before 18: 00, and for the whole day after 18:00.

You can apply to the hotel specifically, maybe it will be free.

I suggest you ask a familiar person, that is, do your homework and design your itinerary to give you a general understanding of Sanya, which is more convenient to arrange, at least you won't be cheated.
