The closest airport for Interface '01 is Orange County Airport (sometimes referred to as Santa Ana Airport, or John Wayne Airport), which is within 5 minutes drive from the Westin South Coast Plaza Hotel. Orange County airport is served by Alaska, America West, American, Continental, Delta, Northwest, Reno Air, Southwest, TWA, United, and US Air, and has direct flights to most parts of the United States. In the Baggage Claim area there is a courtesy telephone to the Westin Hotel, which can be used to arrange for the courtesy van that leaves every half-hour (on the half-hour and on the hour). Taxis are also plentiful. Rental cars are available from the Baggage Claim Area.
Los Angeles International Airport (LAX) offers international connections as well as more non-stop scheduled flights to US locations. It is located further away from the conference hotel, about a 45-minute to 1-hour drive (depending on traffic). On the island outside the Baggage Claim Area, both shuttle vans (about $25 or $30) and taxis (about $65) are available. Rental cars are also available adjacent to the Baggage Claim Area.
For attendees who wish to do some sight-seeing in the Southern California area while visiting, a rental car is probably a good idea since although there is quite a reasonable public-transportation system in the area, most attractions, restaurants, etc., require a car to get there. For attendees who are just planning to attend the conference, a car is not necessary since there are plenty of restaurants within walking distance of the hotel.
