OK, you fly for free. But you have to rent a car, stay in hotels or cabins,eat out every meal.How much is all that going to cost? I remember our first trip to Disney World in the 80's. Friends flew down,stayed in park accomodations and ate every meal out. We drove down with the trailer, stayed in Ft Wilderness, cooked most of our meals and it was half the money our friends spent. So just compare the cost of both. Plus it you are 62,you can stay in any federal campground for half price. We stayed in Madison Campground in Yellowstone for $13 a night. Most stops on the way out were at state parks where the most we paid was $26 a night.We ate out maybe 5 times in a 2 week trip. The rest of the meals we cooked ourselves.
