Editor's note: Cruise & Maritime Voyages has ceased operations and is no longer in business.
Launched in 2010, UK-based Cruise & Maritime Voyages offers low-cost cruises drawing mostly retired British travelers. The line started with two older ocean liners but now has six ships, including one river vessel. You won't find the high-energy entertainment of mainstream cruise lines here — on this much more traditional set of ships, the focus is on the destination. Itineraries span from Australia and New Zealand to South America and the Norwegian fjords, and itineraries include roundtrip sailings from the UK.
