I went to this tonight and thought it was fun. I’d recommend it. When else will you have an opportunity to drive thru a park?
We got in free since we’re members, but we did buy the family snack pack. It was $50, which is a lot, but you do get a lot of stuff. It had 4 hot chocolates, a box of a dozen chocolate chip cookies, a large bag of popcorn (about the size of a grocery store bag!), gummy bears, welches fruit snacks, and a Superman popcorn bucket.
You enter at the normal parking gates and show your tickets. We were at the first reservation time of the night and it seemed like there was confusion with some people not realizing you need tickets/reservations.
After the parking lot entrance, you drive around to the back of the park where they give you whatever you ordered. Then you drive thru the park.
Driving thru the park took about 30 minutes. There are lots of lights and performers along the way - dancers, musicians, etc - and music playing. Very nice atmosphere and fun for the kids.
I would recommend it, although if I was paying for tickets, I might forgo the snack pack and bring my own snacks from home.
