I know I try to go during ‘slower’ times and HP brings folks in, anyway, timing means a lot for FJ...evening adding Express changed a dynamic since Deluxe guest can visit when they want.
But DC ate a lot of folks so I do not feel it was as slow as some think just because waits stayed under 30 minutes.
To me, the craziness might start shifting to when the sun goes down, I assume every coaster fan would enjoy an evening run...then the castle shows...yet I bet most early afternoons (in the slow seasons) might be the best time to visit after this opens.
Does the park stay open late enough to even get night runs? When I lived there the park always closed around 7-8.
