Several years ago, our primary care doctor took his wife on a cruise, partly after hearing us talk about ours. His wife had a severe, sudden allergic reaction to shrimp. He said that he took her down to the ship's doctor and insisted on staying by her side. He said that the ship doc did everything that he or any medical facility in the U.S. would do. He was very impressed by them. I don't remember what cruise line they were on.
