my favorite thing in vegas was Bouchon at the Venetian, lol! expensive, though, but i'm a foodie. hee!
the shops at the forum for mac pro like mentioned above, as well as for the fountains and statues to snap pics of (some of my shots are on display at Nevada State College, hee!) at Ceasar's. The water show and conservatory at Bellagio, the random coaster at Paris, and the lions at MGM, and lots of cirque du soleil shows (Zumanity at NY NY was hilarious! adult show though). lots of stuff to see and do!
