I made a reservation for California Grill at 9:15pm next Sunday. My wife thought that would be too late, despite Extra Magic Hours, so we are going to go to Citricos instead at 7pm.
If anyone wants my CA Grill ressie (for 2 people), send me a PM. You should be able to show up early to see the fireworks. If they can't seat you early, you can go up to the observation deck to watch them. I'll likely be standing with the crowds by the castle at that point.
