Royal Caribbean International spokeswoman Cynthia Martinez said symptoms were reported by 209 guests among the 5,796 people aboard.
Martinez told the Associated Press: "Those affected by the short-lived illness were treated by our ship's doctors with over-the-counter medication."
The statement comes after 220 people fell ill on a five-night cruise in the Caribbean.
According to ABC News, passenger on Royal Caribbean's Independence of the Seas came down with a gastrointestinal illness during the cruise which left Fort Lauderdale on Monday.
Passenger Tracy Flores said: "It was just terrifying - just the amount of people that were coming in at the same time with vomiting and diarrhoea and just looked ghastly."
