Do you use the swimming pools on cruises?

Every cruise so far. I like to swim . Occasionally use the Hot Tub. I also have one at home.

I have never been in a cruise ship pool. I will sit around the pool on a warm day but not go swimming. I rarely use the Jacuzzi on a ship either, as a friend of mine called it "People Soup" I have a private Jacuzzi to use at home where I know it is clean and chemicals balanced before use.
