It doesn't...for people who use Early Entry.Am I missing something - how can a 1-Day LL replace early entry every day?
But based upon Disney's claim that early entry was very lightly attended--and the positive feedback from guests who have attended and found very light crowds--a lot of people aren't taking advantage of EE. If that's the case, getting one LL is an upgrade for them. Though I think it's unnecessarily stingy to not make it one LL per night rather than one per reservation.
