Hi Beth! Thanks for bringing your question to the Disney Parks Moms Panel, and I have great news for you!
The reason you may have not been able to book the Fantasmic! Dining Package at Hollywood & Vine on May 6 is that this dining location transforms May 4 to June 14 to an intergalactic buffet with characters from a galaxy far, far away. The greatest saga ever told will be celebrated at
Jedi Mickey’s STAR WARS Dinner at Hollywood & Vine with Jedi Mickey, Princes Leia Minnie, Darth Vader Goofy, Storm Trooper Donald, and Ewoks Chip & Dale. Young padawans can behold the force of specially designed buffet items and intergalactic music. The force must be strong with you to get an Advanced Dining Reservation for this special meal, as it does fill quickly. Be sure to check for available times online, or call (407) WDW-DINE or (407) 939-3463. Guests are able to book this special dining event during
Star Wars Weekends at Disney's Hollywood Studios with or without the Fantasmic! Dining Package. When looking online for daily availability, I found that this dining experience is listed as a separate choice from the regular Fantasmic! Dining Packages, so this may be why you could not previously find it.
I hope this information helps you with your reservation. Please let me know if you have any further questions. May the force be with you, Beth!
