Yeah I don't see any issue with her riding anything that doesn't have any kind of upper body restraint. Kong, Spider-Man, Cat in the Hat, and other rides like that shouldn't be an issue.
Like I said previously I don't like frivolous lawsuits like this, but this is one thing that is a little annoying in that all the parks have very inconsistent rules even with similar rides. Obviously safety is most important, but at the same time people shouldn't be turned away from rides without any real logical explanation backing it up.
I think there's a possibility this whole thing was set up, but if not I can understand her frustration. I talked about this in another thread but I went to Knott's Berry farm once and discovered I wasn't allowed to ride any roller coasters due to wearing glasses, it was very disappointing to discover I couldn't ride the majority of stuff I was looking forward to even though it was similar to rides I was accustomed to riding. It's very hard to respect rules that just don't seem grounded in any logical reason and then that in turn causes you to question the safety in general. Do they really know what's safe and not safe or are they just taking the approach of applying heavy handed rules since they're really not sure and hope that they eliminate any possibility of anything happening without having to really take a hard look at what the ride does and what's really needed.
