You also have to sign an injury waiver. Also note that while the skating is supervised by the professionals, they aren't going to be conducting classes on doing salchows and lutz's. On the Liberty last year this woman showed up with her daughter and threw a fit because all they were doing is basic instruction on how to skate for those who needed it. Apparently her daughter was a good skater and she thought they would be doing classes on all the jumps and spins. It is amazing what some people expect!
