We went to Christmas in Color at Valleyfair on opening night, and had a great time!
We were there 30 minutes total. Our ticket time was for 5:30pm – 6:00pm but we arrived around 5:15pm. There was already a line of cars but they were already going in so we didn’t have much of a wait and the line kept moving.
Here’s the view from entering the parking lot:
The entrance had a huge lighted “wall” that cars drove through.
