Wife and I will be in our Princess cruise in a few days and she doesn't have a log in account with Princess (her second cruise but first with Medallion) nor she had the medallion apps. I manage everything from booking and check-in so she doesn't need those thing. We are getting the Princess plus package for this cruise and WiFi is part of the package, does she need the medallion apps to get access to Wifi? If she download, does she need to create a separate log-in?
