How much is it to check in at 7 am and check out at 2 pm that day?

I belong to Yantai area. Generally, in Yantai hotel, people in this situation charge a full-day room rate.

Or when you check in, you can tell the front desk that you need an hourly room (sometimes called an hourly room or lounge), and charge by the hour according to the length of your stay. You can compare it with the full-day room rate to see which one is more cost-effective.

Another situation is that some hotels will open a daytime room for you, usually from 8 am to 6 pm, and the room rate at this time is much cheaper than the whole day. After getting off the bus, you can go to a nearby hotel to ask and compare before you check in.
