What age do you have to be to get a membership

I got my son a membership when he was 13

My son is 8 and he comes with me. But hes a guest not a member

You might have to be 18 to get a membership but you can get different types of membership where you can add kids on it

I am not 100% sure but I do know there are family memberships as I have seen children around 12 on the floor or in the classrooms. They may need parents present to work out.
