This is actually very interesting to me. I just priced out WDW vacation the other day for Thanksgiving week (Sat-Sat) and I was quoted $2400 for 8 days at the Carribean Beach Resort, park hoppers (Magic Your Way) plus water parks & free dining -for a family of 4 (technically 5, but #5 is a baby). I do think it's the free dining that makes it seem like such a better value. Unfortunatly for us, coming from the west coast, airfare does us in. Because even at the best value of say around $300/ticket, that's still an additional $1200 (if the baby flies as a lap child). It's still a great deal, IMO for 8 days, but makes it unreachable for us.
For us, going to WDW will be a "big" vacation for us when it happens. So because of that, we're waiting until the kids are all a little older and can really enjoy it...and can handle the difference in ease of getting around
I keep saying I'm going to save for us to do a trip to WDW, but I can't seem to stay away from DL, so I always plan another trip there. If I were to actually skip 1-2 trips to DL we could easily do WDW. But like I said, I have no willpower.
I do want to get my family to WDW though....someday.
