There are a couple Gold's out there. Ask Wiggs to pick you up. They're about $30 a day. The MGM has a decent gym in the hotel, schmooze the whore at the front desk for a couple free passes.
As for strip clubs, go to the Saphire day club, they put a pool outside of the strip club and the whores work the pool. The view is insane. Say hi to Steph for me, she's the hot platinum blonde that works there.
Spearmint Rhino is the only all nude club still in vegas, but very expensive and attracts the "big ballers' rich blacks, iranians and such trying to show off their money.
Just chill at Wet Republic. Don't wait in line like a bitch. Walk to the front with confidence, give the bouncer a nod, show him your hotel key and tell them you are checking it out to see if it's worth it.
Buffets, well it's an endless list of choices, but all will just leave you bloated with the amount of sodium, so be ready to spill over the next day. Bring some diuretics so you can piss out all the water retention overnight and be lean for the pools.
If you're there over Sunday night go to Sunday night swim at XS. The BEST night you'll have. It is a giant night pool party and the whores are fucking insane.
I think TommyWishBone lives in Vegas. Try to meet up with him and Wiggs
