The Venetian is one of my favorite hotels in Vegas. We've been to Venice, Italy and they've done a pretty good job of recreating the Venetian experience, Gondolas and all.
The "All Suite" concept makes every room stay comfortable. Whether it's my wife and I or a guys weekend, there's plenty of room for everybody. I also love the attachment to the Palazzo Hotel. We were recently there on a weekend when temperatures reached 117*. We spent almost the entire weekend in the two connected hotels and didn't feel like we missed a beat.
Both hotels have great restaurants, bars and nightclubs. We'll be back again and again!!
