We love all of the night shows. I just wanted to tell you, though, that you may want to consider the show schedules when planning which ones to attend. On our recent trip in the spring, we made it to Spectromagic and Wishes one night, but it took days for our kids to recover from being up so late.
For our upcoming Dec. trip, I'm hoping to take the kids to Spectromagic, Wishes, and Fantasmic which have traditionally been at reasonable times in the winter months. But my understanding is that Illuminations is shown at 9:30 p.m. during the winter -- too late for my young children.
Also, due to
MVMCP, Wishes is only shown to the general public on certain days (non-MVMCP days), so there is only one day during our trip when we could see Spectromagic and Wishes during our upcoming trip. And, due to Pop Warner, MGM is scheduled to close early on the Friday of our trip, so in all likelihood, we wouldn't be able to see Fantasmic on Friday. Also, I try to schedule late nights/early mornings away from each other, so we may be lucky to make it to just Fantasmic or just Spectromagic/Wishes.
I hope this helps!
