We go about 6x/year - we fly if we are going for less than a week or can't get good airfare. (although if I can't get good airfare for a 4 day weekend trip, I reschedule it usually) There are 4.5 of us now (our oldest dd is at college - it took a while to get used to planning trips without her but that's a whole 'nother thread!

) the .5 is still a lap baby so really just 4 to worry about airfare for now but I know what you're talking about - air can be crazy. The drive is 10 hours without the baby - longer now that we have to make stops more frequently for him - so we only drive if we're staying over a week - it's just not worth the drive otherwise.
One thing we do to make it more affordable is dh & my ap's renew in Jan., the kids renew in June - it helps a ton to spread out that expense - especially since we do the premium ap's.
Also - everyone doesn't go on every trip - like dd (10) and I went w/ a friend & her dd in February, dh flew down for the last weekend of the week. And in October, dh & I do a f&w festival trip w/o the kids (at least we used to - now the 1yo comes with us everywhere.

) Summer trips are always more than a week, and everyone's home usually and we all go then - but as I said, we drive. (also because there are 6 of us and renting a car big enough is crazy, too!)
it's doable but takes some planning - also if we're feeling poor, we'll eat cheaper - and not buy as much "stuff" - lord knows, we have more Disney stuff that we need already.
