NBC News reports no serious injuries were reported when the fire broke out early Monday as the Royal Caribbean Grandeur of the Seas cruised toward CocoCay, Bahamas.
Several passengers, however, were treated for fainting, high blood pressure, and an ankle sprain.
The cause of the fire has yet to be determined. The U.S. Coast Guard and the National Transportation Safety Board have flown to Freeport, Bahamas to investigate.
The cruise, which left from Baltimore Friday night, was supposed to be a seven-night cruise through the Bahamas.
