I have some great memories of watching Wishes from the balcony of the Contemporary one year and from our patio at the Poly. Didn't need to be in the hub with 3 whiny, tired kids. I was able to let them climb in my lap and fall asleep. IIRC, they played the music on the TV during this.
Now, they're all grown up (well, almost) and we got to see HEA in the hub back in 2017. Incredible projection mapping on the castle. Music was much better through their sound system. So much going on. I really needed multiple viewings to take it all in. It is a great replacement for Wishes. But, you would definitely get less if you saw it from CR or Poly today. I'm hoping they do the projection mapping down main street to distribute the crowds better.
