How long can I stay in the hotel a day? When do you usually check in?

It depends on whether you pay in advance or cash. Usually you can check in at noon 12. If you care about the hotel check-in time, I suggest you register as a member in the hotel. For example, I have a member of Mo Lifeng Hotel who can keep it for you until 7: 00 or 8: 00 p.m., and there are small gifts for you, which is quite cost-effective.
