Hi Charity!
Thanks for bringing this question to planDisney!
Guests will not be able to book and purchase
Lightning Lanes until their Lightning Lane booking window opens closer to their trip. So, at this time, there’s no way to tell if the Lightning Lane services will be sold out for those March dates.
If you’re staying at a
Disney World resort or select good neighbor hotel, your booking window will open at 7 AM Eastern, 7 days prior to your resort check-in date. If you’re staying off property, your booking window will open at 7 AM Eastern, 3 days prior to the start date of your ticket for date-based tickets.
With that being said, you will be able to see the pricing for the Lightning Lane services up to 3 weeks in advance by using your
My Disney Experience app.
The easiest way to see Lightning Lane pricing for future dates is by clicking the "Purchase" button under the Lightning Lane Multi Pass/Single Pass section or the Lightning Lane Premier Pass section (depending on which service you’re hoping to purchase). On the next page, right under the calendar, click the “View Pricing by Park” button. There, you’ll be able to click through each park at the top to see the pricing for the different services over the next 3 weeks.
Hopefully that helps! If you have any other questions as you continue to plan your trip, feel free to reach out. I hope you have the best time!
