We own DVC and most of our trips we're in a one or two BR villa. We eat breakfast in the villa five days out of a seven day trip, and have one CB and one other breakfast out, like to the Kona Cafe or Spoodles. When we aren't staying in a villa we normally stay concierge and eat the breakfast in the lounge.
I don't cook at all, other than to heat water for tea, or maybe make microwave popped corn.
We find that if we eat breakfast out, we only need a snack for lunch. If we eat breakfast in the villa we have a full lunch. We prefer to eat at full service places, although there are a very few counter service places we'll eat at.
Then for dinner we eat out every night, usually at one of the more upscale places.
I would never carry food to the parks, unless breath mints are now a basic food group

. I usually start with a bottle of water, and that's about it. I don't like to feel like a bag lady carting my life history around with me.
We do stop at the market on the way from the airport to the World, and pick up water, beer, wine, soda, cereal, milk, tea, fresh fruit, and some sort of snacks--granola bars or Rice Krispies treats.
