We watched HEA from the hub a couple times and also as part of the Highway in the Sky, from the Contemporary.
IMO, the projections are such a big part of HEA that it's really, really disappointing to watch it from far away. Just not even remotely the same show. From the hub people are oohing and ahhing and cheering and from far away the crowd was like, "Huh," and "Okay."
