Breanna, welcome to planDisney! We are so glad you stopped by and asked us a question! It sounds like you are wanting to maximize your day of fun and I am here for it!
I love to hear that you are thinking about making the most of your one day in the parks by getting a
Park Hopper ticket. This would be my recommendation!
Now you mentioned Lightning Lane, but I think you may be actually talking about
Disney Genie+ service. This is the service that you can pay a flat fee per ticket per day and be able to make Lightning Lane selections for participating attractions. If you are talking about the Disney Genie+ add-on for your ticket, the answer is yes. If you have a Park Hopper ticket and purchase Disney Genie+ you will be able to use it in both parks throughout the day. The great thing about this is you can be at Disneyland park and look at the upcoming Lightning Lane options over at Disney California Adventure Park and make your next selection for that attraction without being in that park.
There are a few attractions that have Lighting Lanes, that are only available by purchasing
Individual Lightning Lanes. These can be purchased a la carte and you do not have to also purchase Disney Genie+. The price varies day by day on these. In Disneyland Park, the attraction is Star Wars: Rise of. the Resistance. Over at Disney California Adventure Park, you have Radiator Spring Races, as well as WEB SLINGERS: A Spider-Man Adventure. You are limited to purchasing two of these Individual Lightning Lanes per day.
Breanna, I know that all these new options can be confusing, but hopefully, I was able to make it a little easier to understand. I think you have the right idea to purchase a Park Hopper and Disney Genie+ if you only have one day to experience Disneyland Resort. This will help you make the most of your adventure! Thanks again for stopping by planDisney!
