Cruise holidays to Cuba continue despite travel warning over baffling attacks

But cruise lines are insisting the problem is limited to US embassy officials, so the island is still safe for tourists. 

Carnival said in a statement: “While members and relatives of the US diplomatic corps have suffered illnesses apparently triggered by occurrences at the diplomatic offices or possibly their homes, none of the more than 475,000 other Americans visiting Cuba this year have reported similar health issues related to their visits.

“We are, of course, closely monitoring and are in touch with US, as well as Cuban authorities, and will act accordingly if anything warrants a change in our plans.

“Please be advised that your visa for travel to Cuba is valid, and there are no issues with your return to the US.
