DO: befriend a promoter, get on the VIP guest list, and you'll zip right on through.
DON'T: bring gum or mints, because they'll assume they're laced with drugs and will confiscate them.
DO: ball out and get a cabana so you have your own private pool and a safe place to store your belongings.
DON'T: bother coming if you have little to no self confidence in swimwear because any confidence left will be shattered by the beautiful clientele/staff.
