Hello fellow Nebraskan!
Sadly, the only options to have afternoon/evening passes are for Florida residents, and they are actually annual passes.
Just an fyi, I did look at the park hours for next week. If you are a night owl, the Magic Kingdom is open to 1:00 am on Monday, 7/25; it is open to 12:00 am on Tuesday, 7/26 & Wednesday 7/27. I thought this way with more time available, you will at least be getting more for your dollar if you decide to purchase passes (hours are subject to change).
Also,
Downtown Disney is open everyday with no admission cost. You are also welcome to visit any of the resorts; and the
Grand Floridian,
Contemporary and
Polynesian are wonderful places to eat, shop, and watch the fireworks.
If we can help with more questions, please let us know!
