So try this for jet lag: fly from SJC to LAX, get there about 4pm. Then dinner with jangmonim and the paterfamilias in LA, killing time until the 12:30AM flight from LAX to Inchon near Seoul, which takes 13 hours, getting you there at 5am or so local time. Then a 3-hour layover as you shuttle to a different airport for the 1-hour flight to Jeju Island off the south coast of Korea. Now, a question for you: do you feel ready to start your full day of enforced bus tourism? The answer probably depends on whether you can sleep on planes…
The Treo is inapplicable and I forgot the USB adaptr for my camera, so no pictrs until I get back.
