bpt – I assume you’re kidding but in case a 17 yo does not realize that….Quite dumb to take a room under the name of a random 21 yo stranger in the lobby. That stranger can get a key card from the front desk and enter the room at any time w/o permission, stealing from and/or assaulting the 17 yo.
Toi and Think First are correct.
btw, do these 17 year olds have parents???
