Back in 1992 our first trip to WDW we did a all inclusive plan it was called "The Grand Plan", we did it a few more times each time we saved our receipts and I did the math when I got home. Needless to say the first time we did not get our moneys worth, and after that you really had to take advantage of every thing in order to do so. It included 3 sit down meals a day, 2, snacks, all sports recreation(from mini golf to parasail),fireworks cruise,babysitting, room service and so much much more. One day we even enjoyed room service by the pool. It was a great plan it even included golf and tennis lessons. You really had to plan out your trip to the minuet and use every bit to get your what you pay for it. Even back then it wasn't only an additional $40 to $80 a day(even for a child) it was somewhat more!
In later yrs our family grew and it just wasn't afforadble. We also found that we wanted to be more spontanious and not be to a schedule around our meals. Not to mention 3 sit down meals a day is very hard to do. It included everything from counter service hot dogs to even Victoria and Alberts.
Thanks to this plan though we were able to experience many things that I would probabley never play for seperatly. The price for this today 20 yrs later I would hate to ask!! I know I could never afford it today.
