Santa Clarita-based Princess Cruises will resume U.S. operations beginning in July with a partial season of round-trip sailings to Alaska from Seattle.The announcement was made last week, following the passage of the Alaska Tourism Restoration Act, as well as updates to the Conditional Sail Order put in place by the Centers for Disease Control and Prevention in November.Passengers and crew must be vaccinated in accordance with CDC guidelines and will undergo screenings prior to boarding the Majestic Princess vessel. Dining, entertainment and shore excursion details have not yet been finalized, may be subject to enhanced COVID-19 precautions and limitations, and will be communicated to ticket holders. Sales for the seven-day trips began Friday — the first voyage, departing July 25, is already sold out.“We have been working towards this moment to return to service for over a year and starting with our Alaska cruise vacations is incredibly gratifying,” Jan Swartz, president of Princess Cruises, said in a statement. “Our passion has always been to provide our guests with a truly remarkable travel experience. We are thrilled to be able to do that again, safely with confidence."As part of the updated ‘Cruise with Confidence’ policy onboard, guests may cancel their trip for any reason up to 30 days before departure and receive a future cruise credit for any cancellation fees and a refund of additional funds received to the original payment. Guests who are diagnosed with COVID-19 may cancel their trip and receive a refund up to the day of departure.
