It's a stunning resort, well worth touring even if you don't stay there.
The rooms are spacious, the restaurant choices are unique and inspired, and the central area.........well, you just have to see it to believe it! Very much along the 'Disney' lines, with a dramatic Everglades area, a sort of 'Florida Keys' area, and a Spanish inspired area.
While I did not have time to dine at Old Hickory Steakhouse, I found both Villa de Flora and Sunset Sam's well worth trying. Fresh food, and lots of it. Dessert at Sunset Sams was very good, if I recall correctly.
I can definitely recommend Gaylord Palms, not only for excellent accommodation throughout your trip, but also as a special treat for dinner a one-night stay.
