My DW can't go on anything that is jerky or rough or drops or takes fast turns...basically everything except the shows at WDW. We are going to AK for the first time ever later this week. I thought she would be able to handle a nice safari and to see the animals in the wild. She was looking forward to it too. Then she read in Birnbaums Official Guide about how bumpy it is with all the potholes and it's really a rough ride. Well, now she doesn't want to go on it. How bad is it really? She has had back problems and can throw it out even if I break too hard in the car. Should she avoid this ride? What do other people avoid with bad backs? I know Disney has to post all those warnings for liability reasons, but how bad is it really? Thanks.
