If you're picking up or dropping off passengers at San Diego International Airport, keep in mind that both arrivals and departures share curb space in front of the terminals.
Traffic is always heavy, and airport security is vigilant.
Don't leave your car unattended or linger longer than necessary. Sometimes a special event deserves a special touch. Ask your hotel concierge or receptionist to help you arrange for private limousine service to drive you in style to the wine country or a restaurant or even for a day of sightseeing. Enjoy a bit of luxury. Make sure the rental agency allows its cars to travel across the border.
