We just got back, loved "Wishes", and are not fans of the new show at all. The technology is impressive, but we missed having a cohesive narrative, and we were not particularly fond of the music. The hub was insanely crowded, and although we were standing in what would normally be a great viewing spot, we could only see the top 2/3rds of the castle, so missed many of the projections. Then standing that close, we didn't get the full effect of the fireworks.
The next night, we were at the party and watched Hallow-wishes and it was perfect. I agree with those who would prefer a separate projections show rather than this sensory overload experience.
