Hi Mindy:
In my experience, although weather changes, I find that the weather late October can get crisp at times, but it's usually not too cold to swim, and Disney Resort and Waterpark pools are heated all year long. If you are choosing a Resort and the pool is the most important factor, then either the
Yacht or
Beach Club is your best bet by far. Few people will disagree that Stormalong Bay (shared by the Yacht and Beach Club Resorts) is the best pool on property with a major water slide, several sections, and a lazy river. If you want a Resort on the monorail, I would look at the
Polynesian, which also features a great pool. Another great Resort with an awesome pool is
Animal Kingdom Lodge's Kidani Village, which features Samawati Springs, a 4,700-square-foot, zero-depth entry pool with a 128-foot long slide.
Enjoy your vacation.
