Hi Courtney,
What a fun question!
Disney's Art of Animation Resort is my top Value Resort pick for toddlers. The theming and decorating is larger than life, it truly feels like you are in some of Disney's classic animated films. We stayed at this resort with my then four year old and she still insists that is the best Resort ever! She spent hours just wandering around, looking and playing in all of the different areas.
Other than atmosphere, there are a few other features that make this Disney Resort my preferred resort for toddlers. First and foremost, transportation. Disney's Art of Animation Resort does not share buses with any other resorts when traveling to and from theme parks, which significantly cuts down on travel time. I found that the buses came frequently, and there is only one stop at the resort as well, so it was easy to estimate wait times.
Another reason I love this resort for toddlers is the pool. The Big Blue Pool takes you Under the Sea with Nemo and Friends, where your little one can enjoy Schoolyard Sprayground with fun pop up jets and other great water features. The pool is zero entry making it easy for little ones to become acclimatized to the water. There are also great pool side activities for all ages!
Finally, Landscape of Flavors, the food court at this resort is wonderful. It has a great variety of food, and actual silverware instead of plastic cutlery (I really enjoyed this feature).
I am sure that whatever Disney Resort you choose you will be happy, however Disney's Art of Animation Resort is definitely my top choice. Please let me know if you have any other questions as you plan your Walt Disney World Resort Vacation Courtney. I would be happy to help in any way I can.
