All Star Music without a doubt! Preferred is awesome. In addition, ask to be placed on the backside of one of the Calypso buildings. It will be quiet because it is not facing the pool and you will have nice greenery around your sidewalk area.
Pool and food court are close by and you can stay under building awnings during rain and literally run from the end of Calypso to main building. Also parking lot is closer for unpacking and packing if you drive.
Our family has been to WDW over 20 times. We have stayed at all moderates and all values (both in regular rooms, preferred and suites). Music /preferred is our favorite.
AoA just didn't do much for me. It is a great place to visit, but I wouldn't stay there again. Grounds are cleverly and beautifully landscaped and buildings are themed well, but food court is chaos and a Mermaid is a long walk...when already tired from walking all day or want a quick drink. I stayed at Pop only once and it just didn't feel like home. I do like the lake, but that's it.
My kids have grown up quickly during our Disney trips and all give Music a thumbs up! They are 10, 14 and 30. It has something for all ages. Good luck with our choice.
