FWIW, We watched the July 3 (same show as July 4) MK fireworks from the bridge between BOG and 7DMT.
I would reccomend that area for NYE, too, since it’s less crazy than the hub/main area and is still a great show with fireworks all around you...it’s a great location and interesting location for the pyro and taking pictures, you get the large fireworks over Beauty and Beast castle, and the lower fireworks over Cinderella, and you can still see the 360 perimeter ones. (Especially since the holiday shows are not projection intensive)
Plus it’s an easy walk to BOG
