Situated a mere shuttle ride from San Diego International Airport, Aladdin Airport Parking’s garage keeps cars well tended to 24 hours a day, 365 days a year. Motorists can cruise into self-parking spaces and bid private goodbyes to their cars before flights, or leave them in the hands of a trusty valet so they have more time to enjoy coffee and check updated flight specs in the air-conditioned business center. Soft-ride, high-ceilinged shuttles orbit the garage every eight minutes, stopping to scoop passengers up for quick rides to their terminals. Thanks to the onsite detail center, arriving passengers can return to cars so clean they will have forgotten about their requests for souvenir hubcaps. Aladdin Airport Parking is equipped with parking spaces for people with disabilities, and ADA-compliant buses are always available.

Since 1996, PAW Service Center’s ASE-certified technicians have lovingly tended to hardworking automotive innards with preventive maintenance services and repairs. The full-service facility welcome cars in need of new tires, realignments, and suspension work, as well as regular services such as oil changes and air-conditioning repairs. Technicians also perform complete diagnostics to assess vehicle ailments, identifying everything from an SUV with a faulty belt to a hatchback that’s actually a cleverly disguised bike. Customers can pass their mid-service minutes in a climate-controlled waiting area complete with satellite television and free WiFi.

The facilities also feature gourmet markets and customer lounges where guests can relax with snacks and drinks, or use the free WiFi to argue with complete strangers about the implications of Simpson's paradox.
