How old do you have to be to not have an adult with you

You can get a membership and go at 16 but you will need your ID and your parents signature with their ID also.

I would imagine 18 but I can't say for sure. Call them

To go as a guest you have to be 18 to not have a parent or guardian present. You can get your own membership at 16 with parent's signature and go alone as was stated in a previous comment. ID required for all parties.

At 16 with parent's signature and child's signature.
