Another benefit of having a web based platform - no need to download an app and not limited to a small selection of platforms.

Guest who do not download the app will still be able to send messages to other passengers using Princess@Sea, the award winning app that debuted on the Royal Princess.  Princess@Sea allows guests to view the day’s events and activities, their stateroom account, restaurant menus, and other information about their cruise from any smartphone, tablet, or computer.
