It depends on what you are looking for, in terms of amenities and price.
We researched many of them, and found the Buena Vista Palace, Hilton and Holiday Inn seemed to have the best reviews.
I've stayed at the Whyndam, and it was a good hotel (basic clean place to sleep with good location).
We booked at the Holiday Inn. The Hilton was out of our price range, however is in the best location and has the EMH. The Palace was my first choice because of the location for the price. We chose the Holiday Inn to stay with family. However, this hotel seems to have alot of good extras to make it completely worth while, and it's new.
The other hotels seemed to have decent reviews too. Again, it depends on what you are looking for.
