I found a two year old thread about this, so perhaps nothing has changed, but thought I would ask. Last week while on vacation in Costa Rica, my husband got rolled by a wave and hit his head on the bottom, which caused his neck to snap backwards (I guess that's whiplash?).
It was quite stiff for a few days, but it is better, now. I'm of course worried that he'll damage it when we go on our trip to Disneyworld in two weeks, and he won't go in to have it looked at because it's improving.
Bumpy jostling probably won't bother him, but which rides really whip your head around - either side to side, or back and forth?
