My parents are set to return today from their latest cruise out of Florida.

Hopefully their experience was better than that of the 1,987 passengers and 765 crew members aboard the Vision of the Seas, operated by Royal Caribbean International, who were ordered by health officials in Brazil to remain aboard after some 310 people suffered "some kind of food poisoning.”

The ship was allowed to leave Buzios Thursday afternoon and was expected to arrive in Santos around midnight. An agency spokeswoman said passengers who showed no symptoms would be free to leave. Those still ill would be taken to hospitals for treatment, with expenses paid by Royal Caribbean.
