Princess Cruise Lines is a major international cruise operator that markets multi-day ocean and river voyages to leisure travelers. The company runs a fleet of mid-to-large ships that focus on full-service cruise vacations — staterooms ranging from inside cabins to suites, multiple dining venues (main dining rooms, casual buffets and specialty restaurants), onboard entertainment, spas and pools, and organized shore excursions. Princess is known for regular itineraries to Alaska, the Caribbean, the Mediterranean and other global regions, plus occasional repositioning and world-cruise options.

Two technology and programming features stand out: the MedallionClass wearable and the Discovery at SEA partnership. The Medallion device (or app functionality) is used to speed embarkation, enable keyless stateroom entry and support location-based services for food delivery and wayfinding. The Discovery at SEA collaboration brings documentary-style programming and themed activities tied to Discovery brands, adding enrichment to onboard lectures, family programming and shore excursions.

Princess sells directly through its website and travel-agency partners; the site lets you search itineraries by region, ship or date, view cabin categories and manage reservations. Pricing is fare-based, with additional optional purchases such as specialty dining, shore excursions, premium Wi‑Fi, drink packages and gratuities. Customer service channels include phone and online chat for bookings and pre-cruise support; onboard services cover reception, shore-excursion desks and medical facilities. If you plan to travel during peak cruise seasons, expect fuller ships and higher demand for specialty restaurants and popular shore excursions, so early booking is recommended.
