Filing this one for our friends Down Under — and yes, Tim, that means you. Carnival Adventure, the 2,636-guest ship that used to answer to Pacific Adventure back in its P&O Australia days, was nine nights into a Vanuatu and New Caledonia loop out of Sydney when the itinerary hit a snag. A technical issue jammed the ship's pontoon door, which delayed its July 10 departure from Port Vila, which then domino'd into the July 11 call at Mystery Island getting scrapped entirely.

Here's the part I love. The delay alone might not have killed the stop — the ship could have limped in late for a shortened visit. What actually sank it was a beetle.

Vanuatu's biosecurity rules ban vessels from sailing between the country's islands after dark, because a hitchhiking bug called the Coconut Rhinoceros Beetle likes to burrow into palm crowns and quietly murder coconut trees. It was first spotted on Efate in 2019 and has been island-hopping ever since. Arriving after sunset was legally off the table, so Mystery Island became — wait for it — another sea day.

Captain Francesco Bencivenga broke it to guests by letter: "I'm sorry to advise that we will be unable to visit Mystery Island today and will instead spend the day at sea. We sincerely apologise for this disappointment and any inconvenience caused."

The consolation prize: AU$100 of onboard credit per stateroom, plus refunds for anyone who'd prepaid a Mystery Island excursion. The rest of the sailing carried on unbothered, stopping in Noumea on July 12 before returning to Sydney on July 15.

Give Carnival its due here. Adventure was the first ship to return to Vanuatu after the 7.3-magnitude earthquake battered the region in December 2024, and the line clearly isn't about to torch that relationship over one island stop. Respecting the beetle rules keeps the palms standing and the ports open. A missed port day stings, but "we followed the biosecurity law" is a very good reason to skip a beach — and an even better one to spend an extra afternoon at the bar.
