It's not a stupid question. It's in conjunction with lingerie night and both men and women have to have lingerie on in order to get into the casino (which is in the nice shoes disco). Once in, they'll have a casino set up where participants play at the respective tables for play money. Afterwards, you use the play money to bid on prizes. Afterwards, everyone heads out to Paty'Os for dancing, drinking, and fun while wearing next to nothing. The real fun is watching the faces of the unsuspecting people in the hotel lobby as 300 people in underwear and lingerie spill out of nice shoes into Paty'Os.
I would agree. Its a very fun night. For me, the best night of the trip. I'm usually done after dinner after all the pool fun, but this keeps you going.....
