I just found out that during most of my trip in late January, MK will be closing at 7pm.
From what I can tell on thrill-data.com, lightning lanes sell out much more quickly when there are limited hours like this. I've heard that the park is less busy when it closes early but the data seems to show that the lower supply of LL's significantly outweighs the lower demand from smaller crowds.
Can anyone speak to this from experience? Is it significantly harder to get lightning lanes on shorter park days?
