For those of you who have been offered the Fast Pass Plus, I wanted to let you know what happened to me today. I went on the My Disney Experience page and it offered me a 4th FPP on our MK days! For one of the days, I added a special seating area for the MSEP, and for the other, I added Enchanted Tales with Belle. It gave us lots of choices, but I was trying to add things all ages could do.
