Hi Mysha,
Wow-great choices which will make this a tough decision but let me see if I can help.
Disney's Art of Animation is its newest resort. The theming is all about cartoons which is Disney's specialty! With family suites and a super cool food court, this resort is very popular among families.
Port Orleans Riverside is my family's favorite moderate resort. We love staying in the Magnolia Bend mansions. It also allows a quick walk to food and the buses. This resort offers queen size beds as well as a pull out to provide another sleeping space.
Coronado Springs has the Pepper Market which is my favorite food court. The rooms are very contemporary and play area is fun. However, this resort features a conference center so it sees a lot of traffic during the day. If you move further from the conference center, it is a long walk to the shop and food.
Most resorts can add a roll away bed provide you do not exceed maximum capacity.
My choice would be Port Orleans riverside for the location to the parks and the flexibility with beds.
Wishing you a magical vacation!
Beth
