As far as I know, no, there are no exceptions.
The hotel is requiring an adult to sign for the room so they will take responsibility if there is any damage. The hotel cannot sue an underage person for damage, so the parents sign for responsibility. (Underaged people cannot enter into contracts.)
The airline lounge is a different story. It's not really a question of damage, in my opinion, but a question of providing the paying customers with a quiet, adult atmosphere. Underaged people are admitted with some kind of authority figure (parent, etc) who can reign in any bad behavior and monitor alcohol consumption, or (better) enforce non-consumption. The parent can exert discipline that a random adult stranger cannot. ("If I see you sneak off to the self-pour bar, you will lose your car keys for the next two months.)
I do not believe that a lounge front desk person will allow you in without that authority figure escort if they know your true age. I can't speak from any personal experience, as I haven't seen 16 since 1971, long before I learned that airline clubs even existed.
In less than two years you will be able to enter the AC without any issue. Be patient. In the meantime, enjoy being 16. Living without the crushing burden of adult responsibility is fun.
