Thank you @raven24 and @GiveMeTheMusic! We have dinner reservations at 5:30 the first day we arrive, so I'm hoping we'll be done with dinner in plenty of time to hop over to Disneyland for the fireworks. If so, that may give us the opportunity to see them a second time on one of our other nights.
@GiveMeTheMusic - when you say "prime viewing" in front of the castle, do you feel like standing right in front of the castle gives a good view of the projections? I'm used to castle fireworks shows where the castle is going to be the main focus, so that makes sense to me. It's the additional projections for this show that's making it a little tough for me to decide what location we should go for.
Thanks again, guys! You're the best!
The Castle is a projection surface, the center of it all. A prime castle view would also afford you a view of the Matterhorn, which is also a projection surface. You will miss the "enveloping" feel you would get on Main Street proper, where all of the buildings are projected on but the castle is a bit too distant to make out details. That's why I recommend the upper half of Main Street - you can see the castle and you get the surrounded effect. You will not be able to see the Matterhorn.
