For sure! 7DMT, rode it first thing in the morning the first time. Got the back of the train, it was zippy and fun! The rest of the time, we have ridden it at night and its even better! Its amazing at night! Sometimes I see people riding it when the fireworks are going, that would be neat. Anyway, you have to get the only back if you like peppy rides, otherwise its just ho hum. But going around the corners at night is great! We always get into it and shout and scream and sing HI HO and clap. Have some fun!
Test Trak is also neat at night.
Not sure why, probably because I love Tomorrowland at night, but I enjoy SpaceMtn at night even though its in the dark. I'll ride it both times, but there's something about it at night, especially if you can run around a few times.
Tower of Terror! Its GREEAT at sunset and neat at night. Great view of the park, and it just fits with the creepy factor.
