From reading all of the different suggestions here, and all very good ones, it is pretty obvious that what one person does to save money is different than what someone else does, and yet both are happy with the way that they save their money. We usually do pack some food to take along , in a cooler if going by car, and by getting some protein bars if we are traveling by some other way, like a bus or plane. One of the best vacations that I have ever had was one where we went by car and drove down the West Coast of the United States and took a trip to Disneyland. We packed a cooler; but also stopped and had meals at truck stops along the way, and we camped at campgrounds at night. We had tents and sleeping bags, and the campgrounds always had bathrooms and shower facilities. Usually, they had some kind of an office or group building where they had coffee in the mornings, so we could have fresh coffee, and then stop someplace along the way for an actual breakfast. It was a great trip, and we all enjoyed the stopping and camping out, the scenery at the campgrounds, and we saved a lot of money over renting a motel room every night for the trip.
