Even though I was just in Vegas last month for the Lady Gaga concert, I'm fueling my addiciton again in March with a quick weekend getaway. I decided to try Mandalay Bay, since they were pretty generous with the discounted rates and comped me Friday night (I'm a pretty low roller, so any weekend night comped is good for me). My previous experience with Mandalay Bay is me and a buddy taking the tram there, walking around the casino for five minutes, and thinking "this is far away from humanity." But it is a nice casino and I tend to focus my play pretty close to where I'm staying so I don't think the location will be an issue for me. Anyone have any recommendations for restaurants and stuff? How is their buffet? I don't think I've even heard anyone ever mention it. How easy is it to get an upgrade with the $20 trick? Should I even bother?
