We haven't been to BGW since HoS 2019, and my fears are the same as yours. Reading the posts here has discouraged us from making the 6+ hour drive only to be disappointed by a park both my husband and I have been visiting since the 70's.
We are going to see a show in Hampton in early December and have decided to bite the bullet and see for ourselves just how different the park is. I've already reserved spots for Burgermeister's and am now debating whether to attend BGW for two days or visit Colonial Williamsburg attractions on one of those days. Normally, when we were regular visitors, we'd make at least three trips to VA per season and spend three consecutive days at the park, from rope drop til close. A visit to Hershey last weekend has reminded me just how much I love coasters (I've had some health issues and was afraid my old bones couldn't handle the G-forces, thankfully I was wrong!) Hoping that the weather cooperates and that we can experience Pantheon.
We've never attended ChristmasTown, so at least it should be pretty at night.
