How old must you be to stay in a hotel?

some hotels you have to be 18, some 21. where i used to work it was 21 unless you had a credit card then it was 18. you would need someone to put the room on a credit card for you and check in for you(with id)...and if you are traveling alone thats probably not possible!

without a parent I believe you have to be 18.

Must be 21 to check in a hotel for most hotel.

Probably best thing to do is to make a reservation, would it work to have your parents make the reservation for you while they specify that it is for you and how old you are? Actually, I would be surprised if you have any trouble. I would think that as long as you appear old enough to be independent, you have the $, you are reasonably behaved...the hotel wouldn't have any problems.

it vaires from country to country, ask em first prehaps?

you have to be 18 with an I.D

you need to be 18.

Most importantly, you need a credit card. Most places won't take you unless you're 18, and some won't unless you're 21. Have your parents make a reservation first, and then bring their credit card and you shouldn't have a problem.

Most hotels in Boston I have found want you to be 18. Some require that you are 21. Still some others do not have age limits or will allow you to stay particularly if your parents call ahead and make reservations for you. I think there are places that would be willing to work with you, particularly if your parents provide a credit card, etc to hold the room. but you'll have to call each individual hotel to find out their policy.
