So you may be wondering, what’s with the period after “Fred”? That’s the way the first Fredrik Olsen, a Norwegian who co-founded a shipping company back in 1848, spelled it — and the tradition continued as the company helped pioneer the modern cruise industry in the 1960s. Still owned by Norway’s Olsen family — now in its fifth generation — Fred. Olsen Cruise Lines has a quirky charm that appeals to its primarily British passengers (the line is now based in England). Guests tend to be age 50-plus and are fans of its mid-sized ships, low-key ambiance, good value, and wide-ranging itineraries. Don’t expect a lot of bells and whistles, or the latest in ocean-going technology here. But Fred. Olsen offers a quality, traditional cruise experience, complete with swimming pools, Jacuzzis, spas, and stage shows.
