We would like to travel Europe with our children, who will be 10-12 at the time of travel. We would love to drive a campervan and stay in caravan parks? Or hire a car and stay in cabins and B&B's? we have never travelled so far abroad, but have camper vaned our way around NZ? In a combined effort we would love to see London, Paris, Italy and Switzerland? is this all to ambitious in the one trip? and how long would we need? sorry we are travelling Europe virgins? any help would be gratefully accepted.
