Hi Paula! Welcome back to planDisney!
You must be SO excited to begin your stay at the Most Magical Place on Earth! The
holidays are such a special time to visit the Walt Disney World Resort with all the fun festivities and gorgeous Christmas decorations. You will have the BEST time!
I'm happy to tell you that, yes, you can purchase Disney Genie+ on the
My Disney Experience mobile app for just one day of your multi-day visit! If you add Disney Genie+ to your
Walt Disney World theme park tickets before your visit, you have to add it to all of the days on your ticket. However, if you wait and add Disney Genie+ during your visit, you can purchase just one day on the day you want to use it. This is a great way to pick certain days that you want
Disney Genie+ instead of having to add it to every day of your vacation. It is a lot more flexible with this option!
I hope this helps with your planning, Paula! Please let us know if you have any other questions.
