At the time of activation, a ticket will be associated with one Guest. Each ticket holder will have their photo taken at the park entrance. That photo will be used to verify each Guest when they use their ticket for re-entry on the same day as well as on subsequent days for a multi-day ticket.
Individual Lightning Lane passes are limited and can run out throughout the day, especially if a ride is very popular. And no matter how many theme parks you visit, you can only purchase two Individual Lightning Lane passes per day.
