Hi Aeja! Welcome to planDisney! I'm glad you found us to ask this great question.
How fun that you're going to The Happiest Place on Earth today! I love that the
Disneyland Resort Magic Key Pass makes visiting the magic often more possible. You are correct that you can purchase
Disney Genie+ Service on the day of your visit, pending availability. You won't be able to purchase it until you have scanned for entry into
Disneyland Park or
Disney California Adventure Park.
I'm excited for you that you get to see the start of the
Holidays during your visit! It's the most wonderful and magical time of the year to visit, and my favorite. Be sure to check the
Daily Events Schedule for all of the holiday fun. If you have a chance before your arrival, I also recommend looking at the
Disney Eats: Foodie Guide to Holidays at the Disneyland Resort 2023.
I hope you have a great day at the Disneyland Resort! When you have more planning questions about future visits, please stop by
planDisney again. We would be happy to help!
See ya real soon!
Smiles,
Lisa
