No.The vast majority of hotels in the US would not touch this with a ten foot pole.This is not about you as an individual, this is about teenagers and kids in general, and the problems they cause when they are unattended.The issue is not whether your parent consents, it is the extreme disruption that having one or more unchaperoned teenagers in a hotel inflicts on other guests staying in that hotel.Likewise, the wedding ring trick wouldnu2019t fool anyone: no one cares if you are married, we only care if youu2019re old enough to be trusted to not disturb other guests.Hotels are built on one simple rule: donu2019t bother other guests.Anyone who bothers other guests gets told to stop, and if they do not, that person or group is removed.Anyone with experience in hospitality is familiar with the disruption that kids and teenagers can cause when their chaperones are not keeping them under control. This is why school and family groups that include large numbers of kids are often required to have designated chaperones that the hotel can contact when, not if, the kids start misbehaving.That is why the vast majority of hotels in the US will refuse to check in an unaccompanied minor (and many will refuse anyone under 21): because we know from experience that teens and kids get noisy, and cause trouble, when there are no adults around to control them.You could be the best behaved teenager on the planet, and still no hotel would agree to this, because we have seen what happens when someone does agree: the kids throw a party, guests complain, and whoever was stupid enough to approve this gets fired.No one guest is worth disrupting the stays of other guests.
