I am really sorry I missed the first *A Do, and truly hope to make it to the second one. The main reason I was not able to come last time was the mid-week date.

- How many days can you be away to participate in a DO
I'd say Friday-Monday, or Thursday-Monday at a strech.

- How much money will you be willing to spend
Ideally under $1500.

As for ideas, anything in the US or Canada (hey, less immigration and security hassles here) would be good, Asia and Europe are debatable.

I've actually done the Boeing factory tour (with fellow FTer ausTXhiker) a few years ago and found it, ahem, boring given the expertise FTer already have (yes, I know that this is a 777, thank you). If we do it again, I'd hope that it would be a customized and more "revealing" tour.

Maybe we should also consider airport operators as hosts / activity partners, as they have just as much an interest in their most frequent users as airlines do.
