I've sailed on World Traveller. We undertook one of their Epicurean adventures in the Canaries.

Pros :-

It's a small ship with a maximum of 192 pax.
The ships are well built with nice staterooms.
The crew are friendly and professional.
They have an open bridge so you can literally just walk up and ask "permission to come aboard" and you're sat in the captains seat...
Food quality overall is good. When we sailed we had a Michelin starred chef aboard cooking for us with his wife who was a world famous caviar expert.

Cons

They are really an Antarctic specialist. They didn't seem too well prepared for sailing in Europe at the time.
Pre cruise comms are really poor. This is well documented on the Cruise Critic forum and their Facebook page.
You really feel the sea in a ship that weighs just 9,900 tonnes.
They include some excellent specialty dining in the fare. But in reality, they simply don't have anywhere near enough capacity for the small number of passengers to enjoy it. Book it as soon as you set foot on the ship!
Considering their pricing, I would book Azamara or Oceania instead. They offer a better well rounded experience. Unless of course you are wanting to sail to Antarctica.


My personal thoughts are that there's a lot of unfulfilled potential here. But understand Atlas themselves do not own these ships. They simply charter them from another company and I believe this is responsible for a less than 100% customer satisfaction experience. I do want to set foot in Antarctica, and I would consider booking this kind of trip with them. But I wouldn't book a European cruise simply because there are much better companies offering the same itinerary.

Hope that helps.
