Is the parking price the same all day? I know if you pay to park you can leave and come back by just showing your receipt but if say you only go to a park in the evening, is it less? For example, you are staying off site, you take the hotel shuttle to AK, you shuttle back to the hotel when you're done, take a nap, and then want to drive to MK to see fireworks. Would it cost the same to park in the evening?
