As long as it is actually their experience as opposed to I heard that....
We once had a cruise with a hurricane that kept us out of Fort Lauderdale for 2 days. I later was in a cruise discussion group and someone posted how he heard that it was awful and people were throwing up all over the place. Well, I was there, and that is not what was happening. There was a rough day when the Captain took us closer to land so passengers could get cell reception to make calls to their families, their airlines, their TAs, etc., but it was never like the person who was not there but only heard said it was.
