We strongly advise that all guests download and use the Royal Caribbean App available for Apple and Android devices. It has been enhanced with features that are essential to a smooth and safe boarding day and cruise. These features include notifications, online check-in, the new online Guest Safety Briefing required of all guests, and our Guest Health, Safety, and Conduct Policy. Some features are available only via the App, including the Guest Health Questionnaire to be completed by all guests 24 hours before sailing. The App offers key functionality to support guest needs throughout the sailing, important sailing details, ship maps, guest to guest chat, event and dining booking, itinerary planning, steps to assure health and safety, and more. We continually deploy additional functionality to the App. While we provide assistance for guests without access to a smartphone and the App, we highly recommend all guests download and use the App immediately after cruise booking to achieve the smoothest experience and avoid possible delays.
