We went to WDW for years, and I had no idea there was an actual ride there until I read it here two summers ago. I thought the building just had an exhibit.
Based on the comments I read on these boards, I didn’t expect much, and I rode it for the first time in October 2016.
I actually like it. It’s no headliner, but it’s not awful like the Stitch attraction they just closed. Or the Nemo show.
