Sorry, I didnt mention any other activities other than the beach and shopping (guess you know what we do)! There are mini golfs, golf, horseback riding, nature tours (nighttime turtle walks in season, gator viewing, dolphin cruises, etc), fishing trips (including for shark which I frown upon), kayak nature tours, movies, and the other usual stuff. The Dis resort is at Shelter Cove so you have access to many water activities. Over at Boathouse, there is also jet ski rentals (you go out in groups and often see dolphins). Oh, in Shelter Cove by the Harbourside 3 building and mermaid fountain there is a little playground (great for dad and the kids while mom browses in the shops)!
One more thing, my kids are DS 4.5 and DD 1 if that helps.
