Hi Richard!
Welcome to planDisney!
When using
Lightning Lane Multi Pass, you can book each included attraction 1 time per day pending availability. So, yes! You’ll be able to book a Lightning Lane for Slinky Dog Dash on two separate days as long as you’ve purchased Lightning Lane Multi Pass for both days and there are available return times.
Slinky Dog Dash, in particular, does tend to be a more popular Lightning Lane at Hollywood Studios, so I’d try to snag a return time for that as soon as you scan into your first Lightning Lane of the day when you plan to park hop. With a valid park hopper linked to your account, you’ll only be able to make your 3 Lightning Lane pre-selections at one park, but after scanning into your first ride of the day, you’ll open up the ability to book any ride in any park pending availability.
If you don’t see an available return time for a ride you had your heart set on during your park day, check back often to see if one pops up. Sometimes it will surprise you! Just make sure to click through the prompts quickly if you do see that it becomes available.
Remember, your purchasing and booking window for Lightning Lane services will open at 7 AM Eastern, 7 days prior to your check-in date if you’re staying on Disney World property. If you’re staying off property, your booking window will open at 7 AM Eastern, 3 days prior to the start of your ticket if it’s a date-based ticket. At that time, you can purchase Lightning Lane Multi Pass, Single Pass, and/or
Premier Pass for as many or as few days of your trip as you want.
Hope that helps! Have the best trip!
