The Czech swinger's party wasn't nearly as much fun because no one was swapping partners. Couples just kept to themselves and were watching each other but not interacting.

GGG is a full day of depravity and perversion. You register, get a wristband and t-shirt, and hang out before they announce which girls are going to be in one of two rooms. You are free to go back and forth and each shoot lasts around 45 minutes. They serve sandwiches and snacks and there are hundreds of bottles of water around. They encourage everyone to fuel up on water for the pissing scenes, which start 2 hours into the day. You keep going from room to room all day long, if you want. GIrls do multiple shoots so you can pick your favorites.
