Keely:
This is one of those times where you can see the glass half-full or half-empty. The stained glass windows that surround the back wall of
Cinderella's Royal Table will allow only small glimpses of the bursts. This certainly can add an extra dash of pixie dust to your meal. However, if you're wanting to view the
Wishes fireworks display from the restaurant in a similar fashion to
California Grill and
Ohana with their window views or
Narcoosee's with its veranda, you'll be disappointed. Additionally, I wouldn't recommend you rushing through dinner in order to see the fireworks from the back of the castle where you'll depart. After all, you'll be spending a pretty penny for the meal, and I would hope you'd relax and enjoy such a special occasion.
Wishes is such a memorable "must-do" for any Disney guest that if you wish to keep your dining reservation, I would recommend that you either plan to watch it on another evening from outside the park or park hop back to the Magic Kingdom. There's something magical about seeing the fireworks against the backdrop of the castle.
Wishing y'all a magical vacation!
