Thanks for your feedback. It was Joan's distinct impression-- and I have no reason to disagree-- that had she attempted to take a tour and show up at the airport 2 or 3 hours prior to scheduled flight time, as I had been able to do in Jan of 2003, (and yes, it was on a Sunday!) she would never have made it out on her flight-- or perhaps any time that night. (Which might not have been such a bad thing, especially if the airline had put her up for the night!)
If I remember what she told me correctly, she and her fellow passengers with late afternoon flights were discouraged from even trying a tour, despite the fact that this would cost RCI possible revenue, because the line's staff knew that awful things were afoot at San Juan International.
