Hey there Steve,
Welcome to planDisney and thank you for your question! I can certainly understand why you'd have your heart set on your Fantasmic! Dining Package experience at the
Blue Bayou Restaurant. Not only is the food delicious, but it's one of the most serene dining locations in the park, in my opinion!
However, it's also extremely popular. When looking on the main
Fantasmic! Dining Package page, you'll see that the Blue Bayou Restaurant is still listed as a participating restaurant, but when I checked the availability for December 8, I'm only seeing River Belle Terrace as an option. In my experience, this is typically because the other options have already been booked up.
You can still keep an eye on the reservations for that date as it continues to get closer. Sometimes there will be more reservations that become available if others cancel. However, my preferred method if I'd like to dine at a specific restaurant is to use the
Mobile Dine Walk-Up Availability through the
Disneyland Resort mobile app. It's not a sure bet necessarily, but I have frequently found success is getting into popular spots using this feature when I'm actually on-site during a visit. I'd definitely recommend giving it a shot!
Thanks again for your question, Steve! I hope you have a wonderful visit to the Happiest Place on Earth.
Have a Magical Day,
Greg
