Royal Caribbean’s Wonder of the Seas returned to Miami on Monday just hours after departing when a dispute near the ship’s children’s pool escalated into a physical altercation that left two people injured, authorities said.

The Miami-Dade Police Department said in a statement that “a verbal dispute ensued between patrons, which became physical.” The ship’s captain decided to return to port and contact authorities, the statement said. Both individuals were transported to a local hospital for what police described as minor injuries, and they declined to press charges.

Photos from the scene showed at least one person being loaded into an ambulance on a stretcher, local broadcaster WSVN reported. The Wonder of the Seas had sailed from Miami Monday afternoon on a five-day cruise that was to call in Bahamian ports and return to Florida on Friday. The ship departed Miami again later Monday night, according to local reports.

In a statement, Royal Caribbean said its team provided medical care to the adult guests involved and that the company had notified local authorities and was cooperating with their investigation. "As this is an ongoing investigation, we have no more information to share at this time," the company added.

At nearly 1,200 feet long and carrying capacity for roughly 7,000 passengers and about 2,000 crew members, Wonder of the Seas is among the largest passenger ships in the world. The size and confined spaces of cruise ships have been a factor in several recent onboard incidents; in August, media reports described another fight on a Miami-based cruise that left multiple people bruised.

Miami-Dade authorities and the cruise line provided limited details about what precipitated the dispute near the children’s pool. Police said only that a verbal argument became physical and that the individuals involved declined to press charges. The hospital that received the injured passengers did not immediately release further information about their conditions.

Officials did not say whether any passengers were removed from the cruise beyond the two who were treated, nor did they indicate whether cruise staff made any policy or security adjustments before the ship resumed its itinerary. The case remains under investigation by local law enforcement, and Royal Caribbean said it was working closely with authorities.

The incident highlights ongoing safety and security concerns on large cruise vessels as lines resume full-capacity operations. Royal Caribbean and local authorities declined to provide further comment while the investigation continues.
