I haven't been inside, but I drive past it all the time. It looks nice enough from the outside. Not what you'd normally expect from a Double Tree, though. It's goofy, and tropical, and brightly painted.
My biggest hesitation would be its location. It's nice and close to food, etc. (It's right across from a 24-hour Steak 'n' Shake, and walking distance to a Dunkin Donuts.) It's just IMPOSSIBLE to make a left turn out of or into. It's just past a difficult intersection, on the right side of the divided street. (The "Disney" side, lol.) For one night, it shouldn't be an issue, but to save yourself some frustration, plan right now on having to make a lot of u-turns. (Not actually that hard in that area, but it will add a good 5 minutes to every trip -- except for Disney, which you'll be perfectly positioned for.)
