Then add the cost of driving. Including hotels, tolls, food and depreciation of the car. To only talk of one part of a vacation is crazy because that is not how families budget.Why would I do that? The question on the table is the affordability of a WDW vacation to a 1971 family. You took great pains to point out differences between family size and median income and that we need to consider the 1971 aspects of that. Why would I then ignore the 1971 travel patterns. People did not travel by air in 1971, they did not stay 4 days at WDW, and they did not buy vacation packages.
