So I was looking at my itinerary for our May trip, and I saw that on my Epcot day where we'd picked TT that it had Soarin' in my "wish list." And then I added RnR for our DHS day as part of my "wish list." What is this? It says something about adding it to my itinerary if booking times become available. Just curious if anyone's experienced a wish list fulfillment. 

Please, someone explain!
