Joy
The joy in planning the trip. The joy in watching your trip countdown get smaller day by day. The joy in children's faces as they interact with their favorite toon. The joy in getting in just one more ride on your favorite attratction. The joy in just being at WDW. Finally, the joy of knowing that no matter what is going on outside the perimeter of WDW, that the most pressing things that you have to deal with is making it to your ADR's and getting back for your fastpass time.
