Budget-friendly: ASMovies (splashground, fun theming, playground, walking distance to Mcdonalds), Pop (Skyliner), Ft. Wilderness campsite (such a fun place for toddlers...playgrounds, horses, boat to MK and thus easy access to monorail resorts, kids water playground, Chip n Dale sing along, possible golf cart rental).
AoA is a great choice, too...Skyliner, fun playground, great theming, but more expensive. The Little Mermaid rooms are rarely discounted and we can't justify getting a family suite unless the grandparents are traveling with us so we have 6 people.
Moderate: Port Orleans FQ (playground, water playground, cute theming at pool, easy access to Disney Springs) or Fort Wilderness cabin.
Deluxe: I really liked Saratoga Springs for access to Disney Springs, water playground, dry playground, boat to DS, community room, Surrey bike rentals. Resorts like the Poly or the Grand might have more impressive theming but we appreciated all the non-park activities at SSR.
