Sorry, I booked a hotel in E Long, but I don't need to check in until the early morning of the next day. Do I need to send an email to the hotel? Do I need to provide the order number?

Personally, I suggest you call the hotel to confirm the information and let the hotel keep it until the morning of the 8 th.

You don't have to use mail. The hotel has no time to deal with this. You can call directly.

If the hotel has a high occupancy rate at that time, it may be necessary to provide a guarantee (a deposit can be paid near the hotel).

PS Your check-in time on the 8th (before 6: 00) is still 65438+ 02:00 noon, counting from the 7th.
