After spending weeks exploring Alaska, Ruby Princess has returned to San Francisco—but instead of welcoming new passengers onboard immediately, the ship is getting one more round of intensive cleaning.
Princess Cruises has delayed embarkation for its July 2, 2026 sailing following the confirmed norovirus outbreak reported on the previous voyage.
While the delay may cause a slight inconvenience for arriving guests, the cruise line says the additional time is being used to thoroughly disinfect the ship before the next group of passengers begins their vacation.
The good news for travelers is that, despite the later boarding process, the Alaska cruise itself is still expected to depart on time.
Boarding Delayed as Princess Completes Extra Cleaning

Ruby Princess returned to San Francisco as scheduled after completing a 20-night Alaska cruise that was affected by a confirmed outbreak of norovirus.
Rather than beginning normal embarkation procedures immediately, Princess Cruises informed arriving guests that boarding would start later than originally planned.
According to a letter distributed at the cruise terminal, the cruise line launched an extensive sanitation program in coordination with the U.S. Centers for Disease Control and Prevention (CDC) after a limited number of gastrointestinal illness cases were reported during the previous sailing.
As part of those precautions, the ship is undergoing another complete round of disinfection before welcoming new passengers onboard.
Updated Embarkation Schedule
Passengers were advised of the following changes:
- Check-in begins at 12:30 p.m.
- Final boarding remains 2:30 p.m.
- Scheduled departure from San Francisco remains approximately 3:00 p.m.
At this time, Princess Cruises has not announced any delay to the ship’s departure or changes to the upcoming itinerary.
Alaska Itinerary Remains Unchanged
Although embarkation has been pushed back slightly, guests should still enjoy the same Alaska cruise they originally booked.
The 10-night voyage is scheduled to include visits to:
- Sitka, Alaska
- Haines, Alaska
- Ketchikan, Alaska
- Prince Rupert, British Columbia
Passengers will also experience scenic glacier cruising, one of the highlights of Princess Cruises’ Alaska season.
For now, the boarding delay appears to affect only embarkation procedures in San Francisco rather than the cruise itself.
Why Princess Is Taking Extra Precautions
Princess Cruises’ decision follows a confirmed norovirus outbreak during Ruby Princess’s previous voyage.
That sailing recorded a total of 125 gastrointestinal illness cases, including:
- 102 guests
- 23 crew members
Laboratory testing later confirmed norovirus as the source of the outbreak.
Although the affected passengers have now disembarked, cruise lines typically perform another full ship sanitization before welcoming new guests whenever a gastrointestinal outbreak has occurred.
The goal is simple: reduce the risk of any remaining contamination before the next voyage begins.
Cleaning Started Long Before the Ship Returned

The latest deep cleaning isn’t the first effort Princess has made to control the outbreak.
During the previous sailing, crew members introduced a wide range of enhanced health measures designed to limit the spread of illness.
Those precautions included:
- Deep cleaning every stateroom.
- Increased disinfection of public areas.
- More frequent cleaning of high-touch surfaces.
- Crew-served buffet stations replacing self-service.
- Additional reminders encouraging handwashing.
Passengers onboard also noticed a significant increase in sanitation efforts throughout the voyage, with many later praising the crew for their professionalism and constant attention to cleanliness.
Now that every passenger has left the ship, crew members can perform a far more comprehensive disinfection before new guests arrive.
Health Screenings Continue at Embarkation
Passengers boarding Ruby Princess are also being reminded to report any current symptoms of illness before boarding.
Although this reminder may seem connected to the recent outbreak, it’s actually a standard part of cruise embarkation procedures.
Before sailing, guests are routinely asked about symptoms such as:
- Fever
- Vomiting
- Diarrhea
- Other signs of gastrointestinal illness
If a passenger reports symptoms, medical staff may perform an evaluation before allowing them to board.
Following a recent outbreak, those health screenings may receive even closer attention than usual.
Will Guests Notice Extra Safety Measures?
Even after the ship departs, passengers may continue seeing additional sanitation practices throughout the voyage.
Princess Cruises hasn’t confirmed exactly how long enhanced procedures will remain in place, but guests could notice:
- More frequent cleaning throughout the ship.
- Crew members serving food at buffet stations.
- Additional hand sanitizer stations.
- Increased reminders about proper hand hygiene.
These precautions are common whenever cruise lines respond to gastrointestinal illnesses and are intended to minimize the risk of further transmission.
Can Norovirus Continue Across Multiple Cruises?
Unfortunately, norovirus can sometimes spread across consecutive sailings if even a small amount of contamination remains.
That’s one reason cruise lines invest so much time and effort into deep-cleaning ships before embarking new passengers.
The cruise industry has seen several examples in recent years.
For instance:
- Lindblad Expeditions experienced consecutive norovirus outbreaks aboard National Geographic Sea Bird.
- In 2023, Royal Caribbean’s Enchantment of the Seas reported back-to-back outbreaks affecting more than 300 passengers and crew combined.
Those cases demonstrate why cruise lines often choose to delay boarding rather than rush cleaning procedures.
Why Norovirus Spreads So Easily
According to the CDC, norovirus is one of the most contagious causes of gastrointestinal illness.
It can spread through:
- Contaminated food
- Contaminated water
- Shared surfaces
- Direct person-to-person contact
One of the biggest challenges is that infected individuals may spread the virus before realizing they’re sick—or even after symptoms have disappeared.
Because cruise ships bring thousands of people together in shared dining rooms, theaters, elevators, and public spaces, rapid sanitation becomes especially important whenever cases are identified.
A Small Delay for a Safer Cruise
While waiting a little longer to board may not be how passengers hoped to begin their Alaska vacation, most travelers will likely appreciate the reason behind the delay.
Princess Cruises is taking additional time to ensure Ruby Princess is thoroughly disinfected before another 10-night sailing begins.
At this point, the cruise remains scheduled to depart San Francisco on time, and there are no announced changes to its Alaska itinerary.
For guests preparing to board, a slightly later check-in may be a small trade-off if it helps provide a healthier start to the voyage.
