I know that we'll go out to eat quite a bit when we go on a trip, but I also pack snacks and drinks to take along. Yes, it does help save money, but it's also because there isn't always a good place to stop if you're driving. The airplane food might leave something to be desired if you're flying. The free breakfast at the hotel might mean just cold cereal. We might want a snack outside or regular meal times and not feel like running somewhere right then. I feel better knowing that I have something decent Handy if we get hungry.
