The Grand Canal Shoppes at the Venetian are great! Where else can you take a trip on a gondola to Banana Republic!! The main plaza is beautiful and the "shoppertainment" free!
The Venetian is probably the most beautiful hotel/casino in Vegas. It's like a scaled-down model of Venice in the middle of the Nevada desert. It even has gondola rides down the 'Grand Canal'.
This is not Venice, Italy. There is actually a gondola ride which takes you through the hotel's themed shopping center. I decided to wait for the real thing, myself.
Venetian is less successfull replication of Venice atmosphere, but at least they made an effort.
