We're combining back to back tours of Spain and Portugal in May, 2015 ending in Porto, Portugal. We're considering traveling 5 days from Porto, Portugal to La Coruna, Spain to Bilbao, Spain to St. Jean de-Luz, France to Amboise, France to Paris from where we will fly back home. Would it be best to rent a car or travel by train? Any suggestions or problems would be appreciated.
