Take the boat from DD to POFQ/POR, then get out at POFQ and go to the food court to get beignets! Take a carriage ride while you are there, then hop back on the boat back to DD.
Boardwalk ESPN - if you have any sports fans in the group, call ahead and see if anyone you would be interested in seeing is scheduled to be there during your visit. If so, head over to see the sports figure and eat. If no one interested in appearing, go and eat anyways and check out the memorabila. After dinner, walk around to the YC/BC and get "dessert" at B&C. Then finish the circuit back around past Swan/Dolphin, or take the boat across to Boardwalk.
Watch the Electrical Light Parade from one of the monorail resort beaches.
If you want a less challenging mini golf (but not too easy) try Winter/Summerland. Lots of fun Beach Boys music to listen to as you putt.
If anyone sports fans, check the schedule at Wide World of Sports - may be able to catch some event.
Agree with resort hopping - but I also like to check out the various stores at the resorts! They have a variety of merchandise (ex. AKL has African/safari themed items while WL has items that would remind you of staying in the wilderness)
Disney Quest - try the Pirates of the Carribbean (? Is that the right name?) and build your own roller coaster!
