This summer we took a 3 week trip and ate out twice. Once at McDonald's for a breakfast sandwich and once at Red Lobster only because we had two gift cards given to us by our daughter. Otherwise all meals for the remainder of the 21 days we cooked in the camper. Everyone is different in their approach so one scenario won't fit everyone. We would rather spend our money on seeing the sites rather than eating out. I can eat out anywhere, any time but when I'm on a trip I prefer to be conservative in my spending so we don't eat out much. And frankly I usually prefer my cooking over the restaurants.
