I know well how it is done also, you are full of it. These freeloaders have never earned an honest dime in their lives.
So, they could get to Hawaii and back, rent (or borrow) a condo, etc. just for the price of a round-trip first-class (or maybe economy) airline ticket and discount hotel rates.
That's what they pay...after all, it's not their fault they're the President of the United States, and they need to use Air Force One, Two and Three, and have all this security and Secret Service detail, limousines, etc. to accompany them and stay by their sides.
Their OWN expenses, they pay if they're honorable, but that's a pittance compared to the total.
