You ain't nevah lie, Bill Simmons.

From vegas.com:
"The premier pool area in Vegas, Mandalay Bay's seems to be more of a water park.  Covering 11 acres, the tropical park features three exotic pools, water gardens with lush foliage, waterfalls, fountains, a sandy beach, lazy river, and of course, the wave pool, where waves can reach six feet high.

Mandalay Bay has added a topless pool, Moorea Beach Club, where guests can enjoy a European style beach.  Featuring two dipping pools, admission to the club on Monday through Thursday is $10 for women and $20 for men.  On the weekends, women pay $10 and men pay $30.  Day beds for four rent for $125.  A pavilion, an enclosed VIP area with its own dipping pool and amenities, costs $350 a day on Monday through Thursday and $500 on weekends."

Dude, that's hilarious.  They're making men pay more.
