We went to Vegas earlier this month and loved it. I would even go back someday and I couldnt picture myself saying that a few weeks ago..Vegas just never appealed to me.
I found the drinks a tad expensive but the food was usually good value, and you can amuse yourself endlessly by wandering through all the hotels.
We stayed off the strip at the Hampton Inn Tropicana, really nice hotel, away from all the madness of the Strip with a nice pool. When I become a millionaire I will stay at Mandalay Bay.
Saying that, we tried the Minus 5 bar in the shopping mall between Mandalay Bay and Luxor, which was fun. Its an ice bar, for $25 you get one drink (they have a menu of about 6 cocktails that you can choose from and it is served in a glass made of ice) and you get to borrow a coat and gloves to go into the bar that is actually -5 degrees. Good fun..
