In order to check-in into a hotel, the person must be 21 years old.  If the person is younger than 21, then a parent or guardian can  give permission for them to check-in. 1 person found this useful.
Report Abuse. All hotels have an age limit of either 18 or 21. It really just depends on the place. You should call them before you go and check the age that you have to be to rent out a room.If you aren't old enough, then you can get your parents to call down and make reservations and use their credit card to pay and then when you check in, just check in under their name.It shouldn't be any big deal. The price of the room also depends on the hotel. Different hotels charge different prices.or example, obviously a room with a kitchenette is going to cost more than a room without one. And a hotel that is located directly on the beach will charge more for their rooms than a hotel that is about 5 or 6 blocks away from the beach.
