Cloud 9, the most popular local shuttle service to and from the airport, has signature white vans with the sunny palm trees dot the highways, making even shuttle van service look like fun. The service is easy to use; reservations can be made online, by email, or by phone. Rates vary depending on the distance you're traveling, but there's a break in the price with every successive passenger from your party. It's also possible to charter a van exclusively or to arrange for sedan service. Other benefits: advance reservations are not required for trips originating from the San Diego airport; the service employs a wireless tracking system for its fleet so that dispatchers always know where the vans are - helpful when you're awaiting pickup on the outbound portion of your trip.
