What It Cost To Send The Obamas On A Holiday Vacation

The first family's Christmas vacation to Hawaii in 2013 may have cost about $8 million. Of that total, at least $316,000 was for the Secret Service.

That's according to documents obtained by the right-leaning watchdog group, Judicial Watch. The Obamas spent 17 days in Hawaii between December 2013 and January 2014.

But the real cost is from Air Force One. It costs more than $210,000 per hour to operate the plane, and the Hawaii trip took 36.9 hours of flight. That adds up to more than $7.7 million dollars.

It's hard to tell for sure how Obama's vacation compares to the costs of others presidents' vacations. We can compare the amount of time spent on vacations among presidents, though.

As of December 2014, Obama had taken 161 vacation days. At the same point in their second terms George W. Bush had taken 405, Bill Clinton had taken 174 and Ronald Reagan had 390.
