Just so you know what you're getting, many people who buy the package are under the impression that the "Fantasmic! Dessert & VIP Viewing Experience" is a party. Unlike the dessert parties at MK, Epcot and DHS, there isn't a separate party area with tables and F&B stations. At about half the price of those dessert parties, for $39/$19, Guests get a snack box with the following:
One bottle of water
One specialty beverage (alcoholic or non-alcoholic)
Reserved seating area for Fantasmic!
Custom credential with light-up medallion
Light-up novelty cup
They are then directed to the reserved seating area.
