They now have someone permanently at the door checking room numbers during service. They also write the number of guests. Last time we were there they had a sheet with names and room numbers of who has Club access. We were told if your room and numbers of guests was incorrect or not on the list at all they contact the front desk and the people were charged. Now having said that, maybe you would luck out but not worth the risk IMHO. Also, sneaking in is not cool.
