the Seuss Trolley could get a different ride vehicle. I'd prefer one that's fully enclosed with glass windows since the ride already goes 2 mph
it's boring enough that little kids should be able to ride it. 40" is far too high for a PeopleMover-esque attraction.
Cat has no excuse. Get rid of the beloved spinning if that means families get a dark ride everyone can enjoy. Seuss is the last place where a dark ride should have a 36" height requirement (although I'd want 38"-40" for a Grinch coaster). Trolley at 34", Cat with no spinning has no height requirement, and all is well
