Yes, you can cancel a Lightning Lane selection in 2026, but the rules vary depending on whether you have a Multi Pass or a Single Pass. If you have a Lightning Lane Multi Pass (the daily add-on), you can cancel or "Modify" your selection at any time through the "My Day" tab in the Disney app. If you cancel, your "slot" is freed up, and you can immediately book a different attraction or a different time for the same ride. However, if you purchased an Individual Lightning Lane Single Pass (for high-demand rides like Rise of the Resistance), these are generally non-refundable and cannot be cancelled for a refund once purchased. If you miss your window for a Single Pass, you lose the money unless the ride itself breaks down during your time slot, in which case Disney will usually issue a "Multi-Experience" pass that can be used later in the day.
