Depending on what resort you're staying at, I would ask the front desk for anything that might be particular to that resort. For example, WL has a hidden mickey scavenger hunt that my kids went crazy for. We also rented sea raycers one day, and one day rented bicycles and went out to the stables to look at the horses. We also loved watching movies under the stars at night with a whole group of people who were really into Disney.
