Disney site mentions you can book a 4th LL once you use one of the others-we are arriving around 10a for an upcoming trip-if we book a 10a LL-what happens if our flight is delayed? Do those LLs count as used at 11am, and we can book our 4th, or do we lose the ability to have a 3rd at any given time? I am not sure if this has already been announced, or if i just need to sit back and wait until july 24th...thankfully trip is mid august so i have a bit of time before deciding.
