Well the flight is free but opnce you land you better have some money. I was in a position like this years ago where it wouldnt have mattered if the travel was free, I couldnt afford the vacation itself. Now days, people who make $40k a year are barely buying the groceries and paying the light bill. They can't afford a trip involving hotels, eating out or tickets to Disney for a family of 5. Free flight or not.
Your opinion is yours. There are folks that live with in their means and although not rich take vacations that only involve the gas to get there, and maybe a rental something.
I can drive to the Buffalo River in Arkansas, rent a canoe for a day at $40, float through the first national river in the US with no development within 12 miles of each side, and have one heck of a good vacation.
One doesn't need a three star resort to enjoy life.
