Hi, Stephanie! Welcome to planDisney.
I bet you're counting down the days to your Walt Disney World vacation! I'm sure you're walking around your house singing, "I'm almost there!" It's so fun planning your park days with Lighting Lane Multi Pass, knowing you'll have the chance to experience your favorite attractions with shorter waits. It sounds like you're already ahead of the game and ready to make the most of your time as a 
Disney Resort hotel Guest!
Even though you're in California, all booking times for 
Lightning Lanes follow Eastern Time—the time zone for 
Walt Disney World Resort in Florida. Therefore, you'll want to be ready bright and early at 4:00 AM Pacific Time. The 
My Disney Experience app won't adjust for your local time zone, so be sure to plan accordingly (and maybe have a cup of coffee handy!). You might be Grumpy for the rest of the day, but at least you'll have your Lightning Lane's booked!
And before the big day, double-check that everyone in your travel party is linked in your Family & Friends list and that your app is updated to the latest version. That way, when 7:00 AM (or 4:00 AM for you!) rolls around, you'll be ready to start your day with a dash of Disney magic!
Mike
