The Anatole is an AMAZING hotel. It's absolutely huge and due to their relationship with the museum, it's got a walking art tour inside the building where they have real artwork (paintings, sculptures, etc) on display. One of the coolest features is the grounds they have outdoors by the gym/pool. It's nicely landscaped and absolutely gorgeous. Both lobbies are massive and there are all sorts of weird little hallways with neat architecture. I stayed there about a month ago to scope it out and was impressed.
Personally I hate the Sheraton (aka Adams Mark) so I have skipped Akon the last few years. With the move to the Anatole I am soooo there in 13.
