Shuttle service is a low cost service specifically designed to reduce the cost of tourist movements. It's a car rental service that offers vehicles driven by drivers specialized in the transport of passengers between the airports, ports, stations and hotels. The booking service is cumulative and is managed by RomaShuttleAirport. Being cumulative, the shuttle has multiple passengers headed toward roughly the same area. It is a kind of door-to-door transfer service where, through making an online booking, the customer buys one or more seats (depending on need and availability) in a particular shuttle chosen according to the proposed schedule for departure or arrival.
