I'm going to admit it -- I'm not a huge Vegas fan, though with Fix, the Bellagio fountains, Star Trek Experience, and a few other things, I would definitely go again.
This hotel is the place to be. It's got fun and whimsical theming, and they constantly are e-mailing me with specials for $79/night, Sunday-Thursday. Works for me.
The interior is lots of fun and I really, truly enjoyed the experience. I don't think I'll stay at anything older than this place, because now I'm spoiled! ;)
