Formerly Radisson Seven Seas Cruises until a renaming by the Carlson Group in 2005 to give the vessels a deservedly more upscale connotation, this cruise line has transformed itself from a mishmash fleet of oddly different ships to a much more streamlined and modern three-ship fleet. The ships are now owned by Prestige Cruise Holdings, a subsidiary of Apollo Management. The company also owns Oceania Cruises.
