I really enjoyed this place! It's about 30 minutes of drive thru lights and they are awesome! Set to the beat of the music, it's a cool little show. Yes, you want to be prepared to wait a little bit to get in, but on a Sunday evening the wait was only maybe 30-40 min. I don't think that's unreasonable for a popular attraction.
Yes, cars are $35 each if you don't have reserved tickets ahead of time. If you bring a car full of people though I think it's pretty reasonable.
At the end there is a little village with food vendors, pictures with Santa, a craft station and I think a station where kids can write letters to Santa. A few more light set ups that you can take pictures with too.
Overall it's cute and I like the whole drive thru concept.
