I'm assuming you meant the longest at WDW? That's how I voted. That was 9 days. I spent a month in New Zealand, so that would be my longest non-Disney vacation.
our longest vacation was one week to disney, one to key west plus 4 days drive time and a 3 day visit to inlaws ( 21 days) course that was the second trip that year( that was a fun year!)
our longest disney excluxive has been 11 days at wdw plus 5 at vero beach which was a disney hotel but not in the parks obviously. i could stay gone for months..i'm never ready to go home!
