I just checked into a hotel and don't want to stay. Can I check out? How much is the check-in fee if I check out?

Generally speaking, the hotel will not give you a check-out fee. However, if you can find the reasons why you can't stay in the hotel facilities (such as bad smell, poor sanitation, etc. ), and then tell the front desk clerk that you are allergic to these things, maybe you will go to the hospital, and maybe you can check out.

It is wrong to teach people to lie. This is a sin.
