While President Barack Obama's two-terms are not yet over, by the time the next president takes office his number of vacation days is one of the lowest of any modern president. Currently he's still under 200 which is less than half of his predecessor George W. Bush. All other recent two-term presidents could hover anywhere from 150-500 but between 300-400 was common. But even though records are not reliable from the 18th and 19th century, the worst offenders seemed to be much earlier presidents. The worst of the bunch seemed to be John Adams and James Madison who literally took months off in a row. Though for modern presidents, there isn't much of a day-off as they still have to be on-call for anything important that comes up and much of the president's staff comes along for the trip.
