I get motion sickness pretty easily on things that spin or simulators.....Cannot read in the car, etc. Roller coasters are OK for me tho...and claustrophobia is a very slight problem I have that leads to panic attacks.
The thing that I had the most problem with was Back to the Future. When I walked out of that thing I had to lay on a bench outside for over an hour trying to not puke and getting my bearings back..it was HORRIBLE! I cannot even explain to you how I felt.
When I rode Spiderman, I sort of had the panic feeling, but once it started, there was so much to look at and it is so interesting, I totally forgot about it...didn't get sick at all.
The Cat in the Hat was a toss up...It spins, it not continuous, once in a while this way and then that way...didn't make me feel sick, just a little "off center" maybe (not sure how else to explain it).
Have not tried Jimmy Neutron, but plan on taking good old BONINE and not missing it.
