Hi, Suzanne!
Welcome to planDisney, and thanks for sharing your question with us.
I'm glad to share that you don't have to worry about
purchasing Genie+ right now. Guests visiting the Disneyland Resort can buy Genie+ after they validate their
tickets at the turnstiles, so you will only buy it when you get to the park.
Once you do, don't forget to go to your "Tip Board" to select your first attraction as soon as possible to maximize your time!
I'm also happy to share that you will enjoy unlimited
Disney PhotoPass digital downloads with Genie+. This is a fantastic benefit, and I hope you can get many fun pictures at the
Disneyland Resort!
I hope you have an extraordinary vacation in December, Suzanne!
May the magic be with you,
Julie
