I’m still kicking around the idea of going to WorldCon, even though it’s coming up so soon and I won’t be people-starved yet. :-)
For anyone else looking, I checked on taxi fares from LAX to the con hotel and from John Wayne Airport to there: From LAX it’s $80-90, and from John Wayne it’s $30-35. It makes a difference when looking for flights.
UPDATE: Several people have noted that there are shuttles available; having just come from ReaderCon, where there weren’t any shuttles and the taxi ride from the airport was about $60, I hadn’t thought to check.
