Hey Leah!
Welcome to
planDisney!
Planning a trip to the Happiest Place on Earth is so much fun! It looks like your trip is right around the corner and you’re putting the finishing touches on it. If you haven't heard already,
Fireworks at Disneyland Park have returned and
Mickey’s Mix Magic is the current show. You’ll want to make sure you watch it, it’s so much fun!
At this time, theme park reservations cannot be modified. If your friend wants to change her date she will need to cancel her current reservation and make a new one. I just took a look at the
availability calendar and saw that July 20-22 are still open. I'm not sure which park you were hoping to start at but 1 day tickets can start at Disney California Adventure Park and Park-Hopper Tickets can start at either park. Remember, availability can change at any time and this is just how it was at the time of this writing.
Well Leah, I hope you and your friend have a blast at the parks!
Remember, always believe in the Magic!
