We happen to have reservations at California Grill on July 2 during fireworks. We are there June 26-July 3 and are seeing the fireworks at Epcot on July 1, so this is the only night we can do the MK fireworks. Do you think you get the full experience at California Grill? Or are we better off seeing it on the ground if it is our only day doing it?
This is gonna' be a '
what ever is right for you & your family' response.
If it's all about the best place to view the Castle show & fireworks - as if the fireworks were center stage - this is on Main Street, inside Magic Kingdom.
You can also watch fireworks from the Monorail line hotels. In some cases, like CA Grill, from inside a restaurant in one of those hotels. This is about dining & fireworks. The music is piped-in to the restaurants and the lights are dimmed. This too is an experience. But this is not the best view of the fireworks.
My family does both.
So, let's get to your question of full-experience.
I'd keep the fine dining experience at CA Grill. It is a lovely only-at-Disney experience. As I mentioned, it is
not the best VIEW of the fireworks, but the experience is as adult as Disney gets (without being Victoria & Albert).
You have a longer stay planned. So I would suggest you rework your plans to include the possibility of getting into MK too for the fireworks, especially if you are leaning in that direction emotionally. But be advised, however, leaving the MK immediately after the fireworks is an experience some people would rather a one-and-done (or never). More importantly, if you've been part of current Disney planning,
Park planning changes may be more difficult than it sounds with the requirement of Park Reservations.
When Disney made the announcement, I had already made two CA Grill reservations (since we stay in the hotel). I am no longer likely to drop one of them. But what I felt I had to do was also make a reservation inside MK that gets my plan to include fireworks from Main Street.
This is not a 'right or wrong' question - it's about grabbing a bite and getting the best view,
or, the choice that includes a lovely meal with a (often) priceless view of the MK that happens to include fireworks entertainment.
Also, if CA Grill is affordable, if Disney offers a Dessert Party - this is a way to find yourself less hassled.
We enjoy all these experiences. Maybe you can too.
