Worth the cost! We bought our ticket in advance (one per car) and used a coupon code we found on line. This is a drive through event and you need the know how to shut your lights (including daytime running lights off) so they don't reflect off the car in front of you.
When you arrive you tune your radio and the light show is coordinated to the music. At the end you can stop at their wonderland (picture spots, snacks and crafts) and take your time. I recommend bundling up and throwing the top down if you have a convertible.
Merry Christmas!!!!
