Princess Cruises (princess. com) came to prominence in the 1970s during its starring role in the TV series “The Love Boat.” Although the cruises are not specifically child free, adult-accented activities on board the company’s ships include educational programs featuring lectures in cooking, computers, pottery and photography. According to CruiseDirect. com, these cruises appeal to affluent cruisers who like an easy pace, and onboard highlights include a casino and bingo, bridge and backgammon tables. Each ship includes a dedicated quiet space called the Sanctuary, featuring soft music, personal MP3 players and massage treatments. Princess sails from Fort Lauderdale for the Caribbean, through the Panama Canal and up to Vancouver, and on various European and Mediterranean itineraries that can include stops in Egypt, Russia, Scandinavia and the British Isles.
