My wife gets sick on most rides also, but that does not stop her from enjoying the parks. She loves just being on vacation soaking up the sights and sounds.
She will do:
Universal
Jimmy Neutron's- Nicktoon Blast Once eyes closed most of the time.
Shrek 4-D- No problem.
Twister...Ride it Out-No problems
Revenge of the Mummy-She will tolerate it once, twice she is sick
Disaster!- No problems
Jaws-No problems
Men in Black- No problems
Simpsons-Good for one time with partial eyes shut.
E.T.-No problem.
Terminator- No problem
Islands of Adventure
Spiderman- She likes a lot
Dudley Do-Right's Ripsaw Falls-Good for one ride, but thats because of the last drop.
Popeye and Bluto's Bilge-Rat Barges-She loves this also
Jurassic Park-This is hit of miss, I have to beg her to join due to the drop.
Caro-Seuss-el- No problem
The Cat in the Hat- No problem
The High in the Sky Seuss Trolley Train Ride- No problem
We gave not been for WWOHP yet but that is coming up in May. She said she would try once. Good sport.
Then she will do all shows. Hope this helps.
