The Gaylord is awesome! Of course, it helped that we got upgraded to a suite...for free. Mind you, I got the Gaylord for $85.00/night on Priceline. There are 2 pools at the Gaylord. The "Octopus" pool is for families and kids. It is great. My dd (8 years old and not very tall) could go anywhere in the pool because no part of it is over 3.5 feet. It also has a zero depth entry, as well as a cool Octopus slide. The Key West pool is adults only. My dad thought it was nice.
The Palms is huge! It is relatively new and is still very new looking. What we liked best was the pool and the location...very easy to get to and from Disney. I guess what we liked least (aside from Charley) were the restaurants. They are very expensive. Also, parking is problematic. However, since my dad has a temporary handicapped parking tag..valet parking was free.
I think you do need to keep in mind that the Gaylord Palms is primarily a convention center. If you happen to get there when there is a huge convention, as we did, parking is problematic and the place is very busy. That being said...we would stay there again in an instant.
