82 days!
Over a 12 week winter trip, a 6 week May/June trip, and a 4 week October trip. Of course, not all days were at DVC resorts, and some days were just a visit for fireworks, dinner, or Candlelight Processional. And some visits were just BB, TL, PI, DQ, and WWS.
Like Montana Disney Fan, my personal best is 29 days, including resorts and *gasp* off-site just to indulge our love of WDW. As others have said I think that's pretty good for folks who live in CT!
