Welcome to the club Scott!
Splashbar - easy to find - it's located at the rear of the Riviera as you come OUT from the convention room area (before you get to the main cage) ...if you have to LOOK for it I'll be surprised! Just listen for the loads of laughter intermingled with many "woooooooooo"'s
You might need a boat-load of money...even iced tea is $3 a glass, but most alcoholic drinks are reasonably priced.
Swim?..now that is possible...it depends on how much we drink and how far away your room is!
Try to stay at the Riv or at least VERY close by!
Again, Welcome to the club! Woooooooooooooooo!
