Love it!!
Be prepared to drop some $$. If you're staying at Wynn/Encore you can get tickets at the concierge desk. Chairs are free but you must reserve them and spend a minimum of $500 on drinks. It would be worth it if you had 4+ people. There's no where to put your stuff otherwise so try to bring as little as possible.
The music is a mix of club/trance/top 40. The DJ knew how to get the party started.
Bathrooms are clean and well stocked with anything you'd need (perfume, sunscreen, tanning lotions...)
