While I am within that industry, I am in agreeance that architects shouldn’t be involved with attraction design. Stores and food outlets, yet. A local office design Penguin Encounter, which isn’t bad, but nothing amazing. They are also involved with Vortex, DC Rivals and Jet Rescue to just name a few. And none of them have an inspiring designs. SkyVoyager is the ambitious design we’ve seen, but it doesn’t necessarily pay off (which has been heavily discussed before).
I’ve got a couple friends who have worked on a few of these projects over the years and some definitely haven’t become what was originally hoped for. Whether it was budget, creative differences, licensing or original design ideas weren’t working, etc.
