Disneygal, Kids aren't supposed to be driving them, to the best of my knowledge. Definitely not rentals, anyway. The thing is, and I'm not saying in this case, that you can look fine and not be able to endure the parks, physically. Early in one of my pregnancies, I rented an
eCV for an afternoon. I was feeling hot and nauseous, and wanted to keep up with my family. Had you seen me that evening, I would have appeared to be fine and dandy, 'cuz I was.
That is the point so many are trying to state.
The other problem with those things is that they have no brakes. If you walk in front of one, the driver cannot stop on a dime. I just love the folks that walk in front of my mom, and then give a dirty look when she narrowly misses them!
