The line presented the cheque to global humanitarian aid organisation Direct Relief at the Port of San Diego.
For 10 months on every cruise in the line’s 11-ship fleet, guests could make a $25 donation to participate in a fundraising 5K walk during their sailing, as part of the company’s On Deck for a Cause campaign.
"Our guests and team members, who love to explore the world, wanted to do something to make a meaningful difference for families in a part of the world that desperately needs humanitarian aid," said Gus Antorcha, president, Holland America Line.
"We knew our guests were generous, but their support has well exceeded our expectations, with donations totaling $450,000."
