We prefer to eat onsite, but $$ wise you can save eating offsite.
Time wise, it would be a loser for me, depending on how far you go. Anywhere, you would get in traffic, and it could take considerable time depending on where you went. If you have several days, and don't go in the parks every day, then I could see why you would want to go.
This is what I'm wondering. I haven't driven, or eaten out of the World before. Or gone under such a strict self imposed budget, or brought so many big mouths!

So continued thanks for your thoughts.
This trip we will be doing parks from Go to Drop two days, then Fort two days, off and on for about 2 weeks. A bunch of my kids are coming for thier first Disney visit ever.
So we will be cramming time, but I know me, foodie at heart. I hate trading kings gold for something I can cook as easily, and better, for half a peanut.
I know, I know. I budgeted for CS in park, but I know I will be standing in front of Columbia House, thinking hmmm.

$140.00 dollars for clam chowder, fish n chips.....or Sweet Tomatoes for 8 for $40.00.
The next day it will be Pecos Bill, and $ 99.00 for hamburgers (I mean, of course, for the fixings bar)......."but hey, there's supposed to be a McDonalds less than half a mile from here, how about that .99 cent menu for 24 hamburgers....."(talking teenage bulk, here).
And so I will be wondering again and again, "How much time away from the park would that really take?" and "Is it worth it....when, and for what trade off/ price point?"
What do you think

about drive time to fast food offsite, despite what Google says, on
ONsite days?
