You can find Wet Republic behind the MGM's normal pool. You can't miss it - follow the bumping music. They have an annoying guest list here but if you talk to one of the promoters (and you are a group of girls), you can finagle your way in. Easy peasy.
Once inside, get ready for some fun! The DJ plays a good mix of house, hip hop, and top 40. This pool is much smaller than the Palms and the Hard Rock so finding lounge chairs can be difficult - come early!!! The lounge chairs are these weird green plastic things that are really uncomfortable to sit in. Only like an inch of the chair is in the water so your feet are cool but your body feels like it is in HELL. Unlike all the other pools, Wet Republic is a salt water pool. I remember clearly because my eyes were burning hours later. The crowd is typical. Lots of really scary buff tanoxeric dudes and their girl counterparts. Drinks are mediocre. The best days are Saturdays.
