I am everytime enraged when a question like yours pops up.
Our country is getting sicker everyday: one can condemn a child to the death penalty, send a 17 years old to war, but he cannot check into a hotel. Enraging.

Agree with you. However, it seems most hotels also require a photo ID, which likely has DOB.
I'd show the ID if requested, but make no mention of your age and hope they don't notice.
I have this same situation coming up shortly with my son. I'm just hoping they see his credit card and don't give his age a thought.
