Guess it depends on your budget. Are you specifically looking for something to do at night, or anything during the day before you leave. Are you looking for a dining experience or an activity related experience. Maybe a special picture together with his favorite character, a special meal, is he a sports nut, then something like espn etc. How about renting a pontoon boat and doing a picnic while boating on bay lake while looking at the castle etc. you could pick up sanwhiches at captain cooks or any of the mk resort fast food places. A fishing trip, fun but pricey. The options are endless for sure when you are in the magic!! I am sure if you were a little more specific lots of disers would offer you lots of great ideas.
