Aloha Stacy!
I'm so glad to hear you'll be in town for
Halloween Time at the Disneyland Resort!
For the month of October, you're absolutely right--
Mickey's Halloween Party is held on Tuesday and Friday nights.
Entertainment schedules for the Disneyland Resort are generally posted six weeks in advance, which means, there's really no way of knowing what attractions and events will be available that far out.
I can tell you that World of Color is one of the most popular nighttime spectaculars and the Disneyland Resort knows how much guests look forward to that particular show. Let's hope for plenty of Pixie Dust so that it shows during your visit!
In terms of
Magic Morning, those special early Park entry days are held Tuesdays, Thursdays and Saturdays for guests with valid 3+ day Theme Park tickets. It's recommended that guests arrive an hour and fifteen minutes early.
I hope this helps.
Thanks for stopping by the Disney Parks Moms Panel!
Have a Magical time at the Happiest, er, Spookiest Place on Earth!
