How old are your kids? Green Meadows Farm is great for the ten and under crowd. My girls love it.
Downtown Disney is a good recommendation... Always lots to see.
Disney had two of their own putt putt courses, which is fun.
Have you considered Disney Quest?
What about the Medieval Times dinner show? It's excellent.
There are lots of nest things to go at the Disney resorts, even if you are not a guest. Pirate Cruises, watching the fireworks from the beach with the music piped in, character meals, hayrides at Ft Wilderness, Chip and Dales campfire singalong and movie at Ft Wilderness, wandering from resort to resort exploring by way of buses or monorail, etc. there's endless random fun at Disney without paying for a park.
