Some guests just refuse to leave, even when the party is over, it seems: For the second time in six months, Carnival’s Crown Princess, which sails the seas under the Princess Cruises brand, has hosted an outbreak of norovirus. The ship was met at the dock in Los Angeles yesterday by public health officials after more than 170 passengers and some crew fell ill on a 28-day cruise to destinations like Tahiti and Hawaii.

The stricken have been suffering from a gastrointestinal issue caused by norovirus, a Carnival spokeswoman said in a statement, via Reuters.

“Over the last few days, the ship began seeing an increased number of gastrointestinal illnesses, caused by norovirus,” said the company spokeswoman. “In response, we have enacted our stringent disinfecting protocols developed in conjunction” with the U.S. Centers for Disease Control and Prevention.

The Crown Princess is no stranger to the sight of passengers worshipping at the porcelain throne: In April, the Crown Princess saw a norovirus outbreak sicken more than 100 people aboard. So whatever cleaning up was done after that journey, let’s hope Carnival doubled down — especially because the Crown Princess was scheduled to depart San Pedro last night for another cruise, this time to the Mexican Riviera.
