The company said in a statement that 92 passengers and 13 crew members aboard the Ruby Princess were affected by Norovirus, which causes vomiting, diarrhea and stomach pain. The ship is expected to return to Fort Lauderdale Sunday.
Meanwhile, there has been an increase in the number of cases of gastrointestinal illness among passengers on the Crown Princess, which returned Saturday to Port Everglades.
Spokeswoman Julie Benson says the cases do not appear to be related. The cause of the illness has not yet been determined.
All cabins and public areas on the ships are being disinfected, which will delay their next departures.
(This version CORRECTS APNewsNow. Corrects first paragraph to show that the Ruby Princess returns Sunday, while the Crown Princess returned Saturday.)
