I'm going to post something that I'm sure will be seen as heresy around here.
Be prepared for the possibility that you won't like it.
There. I said it. We've been to Disney during Food and Wine numerous times as we used to take our trip during Jersey Week in November. All of the booths just don't appeal to us for a few reasons. First, we like to eat our meals together, not graze and each eat something at different spots along the way. Second, we like to sit down in a cool place and relax during our meals. We don't want to be balancing trays or sitting on the curb or leaning against a wall when we're eating. Third, it's expensive. To put together enough items to make a filling meal costs a lot more than just going to a counter service location and getting a meal. Fourth, it takes time. Rather than standing in one line for an entire meal, you may stand in 3 or 4 or 5 different lines. When we're at Disney, we don't want to spend a lot of time on meals. We'd rather be enjoying the attractions, shops, and shows.
I totally understand why people love F&W. I think it's a great event. Maybe when my wife and I are older and do Disney at a slower pace, we would be into this, but at this point in our lives and with our daughter with us, F&W just doesn't fit the way we like to do the parks.
You have 3 kids so keep in mind that while you or your spouse might want to try things from the booths, your kids may not, so you still may need to do traditional meals in addition to what you eat from the booths.
