Rides I enjoy at night are, Splash, BTMRR, and TTA which make sense. But then the others I really enjoy more at night are Buzz and POTC. I know these are both indoor rides, but I just love going into them when it's dark out, and then coming out after the ride into the dark. Not sure what it is about night time that makes me enjoy these 2 more, but I do.
And if you've seen Wishes or don't care for fireworks in general, that is the best time to be hitting rides.
