The big difference I'd like to point out between BGW and KD is that BGW has the fortune of being located in a populated, suburban area. They can easily fill the park with 1000 guests who live within a 10 minute drive of the park. The value proposition of their 4-hour morning/evening "event" makes sense, since it's mostly for locals who want to swing by the park to fill an evening.
KD, on the other hand, is located in the middle of nowhere. The park is in an unincorporated town in Hanover County and is surrounded by farmland, not homes and neighborhoods; pretty much everyone visitng KD has a sizable drive up or down I95 to make. I live about 25 minutes from KD, and I'd bet that I am relatively close to the park compared to most of its guests, even its regulars and passholders. Considering the hassle and planning needed to travel to KD, I don't see enough people being able to justify the trip in order to fill the park with 1000 guests each day.
Every year on my last visit of the season to KD, I always pause for a second in front of the entrance to soak it all in one last time - the fountains, the Eiffel Tower, the lights, the music. It always makes me a little sad to say goodbye, but I always know I'll be back in a few months. Little did I know in December 2019 then that it might be more than a year before I'd be able to take in that view of my beloved home park again.
Maybe it's just me, but it always feels like I'm on a journey when heading out of town on 95; even though I could drive Route 1 most of the way in only slightly more time KD always seems of the way.
