a) Yes, we do love it that much, although we are going to take a break, and probably won't be back until at least 2005.
b) We afford it by not dining out a lot at home, etc, and going in the off season, and taking advantages of specials and available discounts (I miss Disney Club!). Also, after the first trip, we limited souvenir purchases. Fortunately, for us, that's enough. Of course, YMMV. But if we had to pare down the costs more, we could drive down, and camp at Fort Wilderness (who knows? we may do that next time, anyway).
Ciao,
Mort.
