There will be 6 adults in our party as we visit Spain in September. Flying into Bilbao, then to Barcelona, Madrid, toledo, Granada and Costa del Sol. Looked into trains but think we'll rent a vehicle to get between cities, then park it in favor of public transport while we're in town. Problem is that I'm uncertain that I can fit 6 adults along with their carry-on sized suitcases into a Seat Alhambra or Mercedes Viano or other similar vehicle at the same time and they don't seem to rent roof top luggage carriers in Spain. Plus, I'm nervous about finding parking spaces (secure ones) large enough to accommodate - and equally troublesome is the thought of navigating very narrow roads in Toledo or Granada just to get to the hotel. Does anyone have knowledge or expertise on the capacity of these vans and driving/parking them? My husband is game to try driving one. Thanks!
