Visible crew/equipment: After Luke fixes Lorelai's broken heel it cuts to Lane at the first-aid/rest stop at Miss Patty's, and when Lane walks toward her table, we can see the T-marks taped to the floor. (00:35:10)
Chosen answer: Lorelai and Christopher get married impulsively in Paris but they get divorced shortly after returning home. I don't know the exact number of days or weeks but they definitely weren't married for more than a couple of months.
