OMG!! This is the place in Vegas, IMHO. No other place has it all.
Start with the dancing fountains out front. They can amuse you for hours. Entrance is magnificent. Classy marble floors, and light fixtures made out of blown glass. Wonderful artifacts all over. The Atrium is so unique and so beautiful, you could spend a lot of time just walking through it and looking at the plants and flowers.
The rooms are clean and top tier. Everything was just super in the rooms I have stayed there on several visits. Pool area if real nice and attracts the "it" crowd.
Casino is marvelously laid out. Rich red carpet with pattern throughout. Gold crown molding, blown glass, tapestries, marvelous paintings, and statues throughout. Has it all your need for your gambling needs.
Great restaurants on location. You really don't need to go anywhere else (that's the idea). Buffet is one or the best in town.
To cap it off, this is where the Cirque du Soleil show "O" is staged. I should say the bigger than Olympic pool is used. Fantastic and indescribable show. Think Olympics water athletes on steroids. The best show in Vegas IMHO.
This is a true 5 star hotel, casino, and showplace. You owe it to yourself to visit.
