Passengers were left on a 'crummy cruise to nowhere' after their ship was turned away from New Zealand because it had 4 seashells stuck to the hull

• P&O's Pacific Adventure was supposed to stop at multiple ports in New Zealand, The Guardian reported.
• But it was turned away due to invasive species on the hull, and poor diving conditions stopped it being cleaned.
• Passengers have been suffering from sea sickness, and can receive a refund and $200 onboard credit after an outcry.
