The south rim of the GC is a looong ass drive. Just did it three months ago. If you're doing it for road head you're gonna get callouses.
Hoover Dam/Lake Meade/Valley of Fire (in the sunset) is nice. West Rim GC not much further.
There are pool parties in the day and dj parties at night. There are gay pool parties although nothing like Rehab at the Hard Rock. You go to Vegas for the pools and the big dj's.
"Quieter" is the all-night Pirannha gay strip club and the Grove dispensery across the street from it. Cozy, gay, hip, chill.
