Since most people _should_ arrive at the 8th I'd recon the 9th or 10th for the CC meetup. Cuz I want 2 get 2 know the peoplez a few days before I go home again 2 habe fun togehther 4 a few days. But, since it is at the resort anyway... Why don't make a daily CC meeting somewhere in the resort, say, every day at 3pm the CC people meet at the burger bar or something like that...
yes, once you attend the party on the 9th (probable date) you will form bonds/friendships/drinking buddies immediately and make plans for each day and night. I always end up hanging with someone from CC every night, and we run into others along the way. If we make a rendezvous point at the Oasis for every day (same spot, same time), those staying there or visiting with day passes can easily find others.
