Hello there, Blanca, and welcome to planDisney!
Thanks so much for stopping by with your question and I love how you're embracing technology to help you make a more magical Disney day! I'm a tech geek, so I love these kinds of things and it would be my pleasure to go over Disney's complimentary Genie service.
If you need a little more help planning out your itinerary while visiting the Disneyland Resort, the complimentary
Genie service that's included with the
Disneyland Mobile App is at your service! I'm happy to report that you are indeed able to input your attraction, dining, and show preferences from home before your visit. You must already have a valid ticket and park reservation in order to register your preferences for the day. Just go ahead and make your selections and Genie will do the rest for you! Keep in mind that your Recommendations will populate at 7 a.m. on the day of your visit, so don't fret if you don't see it respond right away.
If you want to take the next step,
Genie+ is a separate add-on to your ticket that may be purchased on the day of your visit after you enter the Parks (if you didn't already purchase it when you got your tickets). This will allow you to utilize Lightning Lanes at select attractions and skip the majority of the standby queue, thereby saving you tons of time throughout the day!
Blanca, I hope that this was helpful for you. If you have more questions for us, please don't hesitate to visit us again because we'd love to hear from you and help you to plan a wonderful Disney day! You're always welcome at planDisney and we'll see ya real soon!
Wishing You a Great, Big, Beautiful Tomorrow!
