Passengers will no longer need to show proof of vaccination or a negative COVID test result to board, though the changes are subject to local requirements at various destinations. The cruise line previously began welcoming all guests regardless of vaccination status on Sept. 3, but unvaccinated passengers had to take a test prior to embarkation.
