There are two unique 21 age limits.

1. Membership: Must be 21 or over to be a member

2. Being considered "family" and allowed in under the membership. As a PC member, when traveling with my family, I can bring in my wife and both of my children (currently both are under 21), for a total of three guests. Once my oldest reaches 21, I'd be limited to bringing in only one of my children. If I had six childern under 21, conceivably I could bring all six in (but I wouldn't do that to myself or to the other club members).

If I'm traveling with my mistresses instead of my family, I can only bring two of them in. My choice on which two of: the 20, 22 or 24 year olds. No age limit on my two guests.
