Well, I said I'd post what we're going to try for.
Today, DH and I are going to find out if we can take off to go to
Disneyland. It's been almost 2 years since a DL trip (Gasp!!

) and we were just at WDW last year. The $300 savings before food and souvineers can really be used elsewhere, then add in that at WDW we'd be doing fancy $80-$100 dinners almost every night (that's half of why DH wants to go to WDW in the first place, so they aren't negotiable to him in a WDW trip) but at DL there aren't more than 1 or 2 expensive dinners that we're interested in trying, so we could end up saving as much as $300 *more* in food, we wouldn't be renting a car (I'm too afraid to drive at LAX) so that saves yet *another* $150 (minus however much it's going to cost us to get to DL from LAX), and finally the souvineers... the main thing I usually come back with from DL is books, CDs, or pins. I usually come back with much more than that from WDW, so I'm guestimating that I'd end up spending/wanting to spend about $100 less at WDW.
That adds up to a heckuvalot of savings for us, and all that money can definitely be used elsewhere.
And for those who don't think DL is worth the trip -- we do! I've easily spent 5 days in DL before, and that was before DCA and DD. We'll have more than enough to keep us busy and can move at a more relaxed pace.
Hopefully our respective bosses will give us the "go" for November!
