Hi there, Paul, and welcome to planDisney!
We're happy to see you here with your question and excited that you're visiting the Disneyland Resort, which apparently is happening as I type this out! I'm sorry that we couldn't address your question before your arrival but I hope that you're having the best time at the Parks!
Genie+ is a wonderful way to maximize the time that you spend at the Disneyland Resort. You'll be able to book
Lightning Lanes throughout the day which allows you to bypass the standby queues and gets you onto the attraction much faster! At the Disneyland Resort, Guests are able to book their first Lightning Lane after they scan into one of the Theme Parks for the day. So although you won't be able to book anything the day before, the earlier you arrive on the day of your visit, the better.
I hope that you're enjoying everything there is to see and do at the Parks! I just returned from a visit with my kids and we had a wonderful time with the
Pixar Fest experiences and got to view
Fantasmic! for the first time since its return (it's just as awesome as we remember)! Have you been able to try any of the
special dishes for Pixar Fest? That Panda Apocalypse from the 4*Town Fav*4*ites inspired by “Turning Red” booth was delicious!
Paul, it was a pleasure being able to help you and I wish you a truly magical visit to the Disneyland Resort! If you have any further questions in the future, please feel free to write back to us. We'd love to hear from you. Until then, we'll see ya real soon!
Wishing You a Great, Big, Beautiful Tomorrow!
