<font color=navy>I haven't visited all the Good Neighbor Hotels, but I did visit a few.
I liked the pools at the Howard Johnson - a moderate hotel. There are two of them -- the main pool also has a kiddie pool next to it, and you can see the monorail from there, and the fireworks, were you to be at the pool at that time. There is another, quieter pool, surrounded by nice trees, and would be ideal for adults. The hotel also offers towels for guests. You can see pics of these pools in the thread stuck at the top of the DL Board that says Good Neighbor Hotels.
Another moderate would be the Coast Hotel, which is a high rise hotel, with a nice pool that has a bar next to it. I have a pic of the pool area that I can upload, if you're interested.
A superior hotel is the Sheraton hotel, and the pool is nice there, as well as the grounds are beautiful.
