Hi Danya! Welcome to planDisney. I'm glad you stopped by with your great question.
If you'd like to add
Lighting Lane Multi Pass to the second date of your visit, you are more than welcome to do so on the day of your park visit after scanning into either theme park for the day. You can do this by paying the daily rate for the Lighting Lane Multi Pass in the
Disneyland Mobile App. The app is also where you will make your ride return time selections.
While I have never personally had a problem purchasing this optional add-on the day of a visit, I do recommend getting to the theme parks as early as you can as it will provide a greater number of available selections for the rides. For super popular rides (like
Indiana Jones Adventure, Space Mountain, and
Soarin' Around the World), the early return times tend to book most quickly. So, if you arrive at the parks later in the day, you may have fewer options for return times on those rides.
Danya, if I misunderstood and you are hoping to switch your already-purchased Lighting Lane from the original day to another day, you may be able to do this by chatting with a Cast Member in the Disneyland Mobile App or on the
Disneyland Resort website. While the My Disney Experience App at Walt Disney World allows this change directly in the app, the Disneyland Mobile App functions slightly differently. It may not be possible, but a Cast Member can certainly help you with your options.
I hope this helps plan a most magical visit, Danya. Please visit us again soon!
