I watched Hallowishes from the viewing deck after eating there earlier in the evening. Thought it was amazing, but that's a show with few projections. I enjoyed seeing what was set off at the castle and what was set off further back. It's a really cool POV. And the finale of Hallowishes is awesome from that vantage point. I forgot how big it got!
If you know HEA well, it would be a fun alternate perspective. If you haven't seen it before, I'd suggest watching from MK first.
