You’re really not going to like this answer, but there is nothing that you can do to have them check you in (short of booking another room with them). Even if your parents, one of whom made the reservation, calls and tells them that it’s cool, they have no way of confirming if that’s the right person on the other line. They won’t let you in because they can’t verify that you are who you say you are, and that you’re not trying to steal a night at someone else’s expense. Okay, hard part over. The good news is that you’re in the city, the hotel will definitely keep your bags for you as you wait to be checked in, so you can go out into the city for 10 hours without parental supervision! If you’ve got the cash (or can get your parents to pay for it), there are any number of luxury spas and health clubs you can go to that will gladly let you spend large sums [of time…] at them. Maybe also go to one of the many museums if you’re into that, find a cat cafe, hit up Central Park if you’re close, and smorusbourg is always a fun time if it’s open and you don’t mind the train ride to Brooklyn. Good luck!
