Please note that guests confirmed on U.S. sailings departing on or before August 7, 2022, should adhere to protocols previously communicated.For those clients booked after August 14, 2022, please await the specific protocol details from us related to those sailings. As we begin to transition to a point where everyone, regardless of vaccination status, will be able to sail with us once again, we continue to work closely with our destination partners. Additional information will soon follow, however, until then, current vaccine guidance remains unchanged.
