What really sells the nighttime experience of the attraction is the lights. Not just the surrounding ambiance of Toy Story Land, but all over the park.
The flood of light is disorienting enough to create an added excitement to the attraction. Then doing that circuit in the dark just makes it even better than in the day.
It’s not as though there is a programmed loop of projections or animatronic movements at work. Animals have their own schedules and many are simply more active at night.
Tomorrowland illuminates at night and fully takes on its futuristic appearance with glowing neon lights bouncing off of metallic facades and otherworldly rock formations.
Not only does the darkness in the outdoor elements make the ride more exciting, but I am enthralled by the warm inviting lights that loom over the outdoor queue in the evening.
