Welcome to planDisney, Arturo!
I'm so glad that you are looking into
Disney Genie+ before your visit to the Disneyland Resort! If you purchased your tickets before Disney Genie+ launched and the option wasn't available, the only way to add it to your tickets is to purchase it daily in the
Disneyland app after you have entered one of the parks. The cost will be $20 per day, per ticket.
In addition to being able to skip most of the wait by using the Lightning Lane on select attractions, Disney Genie+ also includes downloads of all your Disney PhotoPass photos you have taken on any day you have purchased Disney Genie+. So be sure to stop by the many Disney PhotoPass photographers located throughout the parks!
I hope you have a wonderful time at the Happiest Place on Earth!
