We have done the Illuminations Dessert Party, Wishes Dessert Party and the Ferry Tale Wishes Dessert Party. Do you see a theme here?
Of the three, Illuminations was my least favorite. While the view was ideal, there were no seats (although I had done research ahead of time and knew to grab a table near the low wall so I could rest my park weary feet for a bit). The desserts were also my least favorite with some of them tasting like they had come from the frozen section of the grocery store. Not that they were bad, but I felt the other parties had better.
There are so many really great viewing spots for Illuminations, I think having a nice dinner and settling in elsewhere in the park to see the show might be a better use of the money. Just my opinion for what it's worth.
