Hi Don,
Let me first assure you that you aren't doing anything wrong! Any of the dessert parties are wildly popular, especially the
Wishes Fireworks Dessert Party. The party is probably filling up as soon as a new date is available.
If you have only checked online, you might want to call, (407) 939-3463. Occasionally, I have found availability by calling when I couldn't find anything online.
My best advice is to keep checking. Sending you lots of pixie dust that you find an available date that works for you!
Thanks for stopping by the Disney Parks Moms Panel. Please let us know if we can help you with any other questions!
Wishing you a magical vacation,
Amy H
