My friend managed to get us onto the guest list through her promoter and our group of 5 girls and 3 guys got in for free, with no problems.
Other than the loud club music, there's not much difference between a "beach club" and a regular hotel pool. Except you actually have lounge chairs to place your stuff and sit in, while at a beach club, you can only do that if you buy a table/bottle service, which is dumb imo. If I had to choose, I'd pick a plastic lounge chair + book + personal iPod, over loud club music + lounge couches + stripper poles in the middle of the pool to dance on.
Tables start off at $300, reaching up to $1800 for a cabana, which the club suggested we get since we had 8 people. $1800 for a cabana LOL do we look like we're made out of money?? I don't even think we stayed for more than two hours! It was a nice experience, but I wouldn't go back unless a friend (of a friend) got a table.
