Fort Wilderness has plenty as written above with hay rides, pet zoo, and Chip and Dale sing-a-long movie (free). You can also rent canoes, horseback riding and/or bikes. Of course with young ones some of these don't look like options. You can go to California Grill (top of the Contemp.) and have cokes on the deck and wait for the MK fireworks show which is beautifull themed to music. You can wait to see the water pageant at any of the monorail resorts or WL or Fort Wilderness as it goes past all of them. You can walk the trail between the Poly and GF at night and watch the fireworks while the kids play in the sand then catch the Monorail back to the buses. The putt-putts are good. Boardwalk can be fun for the kids at night. You can go to PO FQ or RS and talk the boat for free to DTD. If you want something to do without the kids for one night, then either go the PO FQ or RS bars as they have sing alongs (adult entertainment which is fun). There is usually one night per week at the AS wherein Karoke is held for families (call and ask them what day this is, I'm thinking Tuesdays). Personnally, my fave is watching the animals at AK, several different areas to do this from as well as the storytelling that happens nightly at the firepit.
