Well, my wife uses a travel mobility scooter, obviously not the same thing, but we traveled all over the world with it. Is it comfortable? No. Can it be bumpy? Yes. Are sidewalks sometimes complicated - narrow and with obstructions? Yes. But it is not really different with steollers, but you might reconsider a double wide, and each push one. Sometimes, I need to give my wife a "boost" going up some areas, but again, it is just the way it is. Enjoy your trip, don't be afraid, get something light weight, and in the worst case, you might have to carry short distances but most likely not.
