I was at the Treasure Island Hotel/Casino, my 22st birthday a few months ago. I can honestly say that I love Vegas, but I wouldn't want to spend too much time there. After shows, hotel, food, and airfare, I spent $2,000 on the trip with my family (My dad, sister, and me) before adding in gambling losses . Las Vegas is very pricey.
Although, I can say now that I have gambled in every Casino of the Las Vegas, even if you count the Airport slot machine , I had luck in the Sahara, Bellagio, and Luxor. I lost most money at Caesars, MGM, Stratosphere, and the Carnival Casinos.
By the way, if you want to enjoy the oppulence, I'd take a stroll in the Venetian. It is such an interesting place to visit with its own indoor canal. I hear the rooms are expensive, but extrordinary.
Trebs/Dan, I might head to DC sometime later. If you're doing lobbying there or something send me a PM, we may be able to do lunch.
