Well, two good airports plus SFO. Unless we can schedule a fog-free day.

If done right, it might even be possible to get group tickets to a 49er game -- they have all sorts of group plans. Being from the Bay Area originally myself, I like this idea as well.

As much as I'd love to go to Australia, it does seem a bit cost prohibitive these days.

I would list, in no particular order, some of these options:

SFO (Napa Valley in the spring)
SNA/LAX (Disney! any time of year)
MCO (Disney! in the winter/spring)
COS (Ski Weekend in the winter, with a side trip to visit the House of Randy )
PHX (Scottsdale in the winter/spring)

Sure there are lots of other options out there too, as evidenced by the numerous posts.

Wherever it ends up, I'll do my best to be there!
