KINGSTON, Jamaica (AP) — A Royal Caribbean cruise ship headed back to its home port in the U.S. on Monday after hundreds of passengers and crew members fell ill with vomiting and diarrhea during what was supposed to be a 10-day getaway in the sun.

The Miami-based company announced Sunday evening that it was cutting short the Explorer of the Seas’ jaunt in the Caribbean a few hours after officials from the U.S. Centers for Disease Control and Prevention boarded the ship during its U.S. Virgin Islands port call to investigate the illness.
