Poly lover here! It's so hard for me to say because I don't know what to expect at AoA. I've seen pics and it looks cool. I would love to try it in the future maybe. Here are some of the reasons we love the Poly and prefer to stay there:
- Convenience of Monorail and easy access to MK and Epcot
- Watching Wishes right from the beach/pool
- Electrical Water pageant
- Relaxing
- Great restaurant options
- Well themed
- Greens are beautiful
- Cabanas by the pool, boat rentals
- The Neverland Kids Club
- Standard room sleeps 5 (we are a family of 5)
- If its a day where it's raining, we don't feel trapped- you can take a "monorail resort tour" and essentially stay inside the whole time. Also they have hula lessons in the Great Ceremonial House along with making Leis (great for the kids!)
I can't tell you it would be better to spend the extra money on the Poly bc it isn't my place, but I can tell you that IF you did spend the extra money, that you most likely will not be disappointed. Take a look at the pics in the Poly thread too.
