At VWL they do have the "Hidden Mickey" scavenger hunt sheets (pick 'em up at the front desk); they have ducky races at the pool; and the Cub's den often has afternoon activities (for free) such as arts / crafts, etc. THey also have story hour in the main lobby in the evening (wear your jammies!)
You can also go over on the boat to FW and enjoy the petting zoo or horseback rides... or you can rent the water stuff or bicycles and cruise around.
