Was recently on another cruise line and we bought one internet package. When my wife wanted to get on it would say "This is for one device only - knock the other device off so you can get on?" (okay, it was worded a lot more tech-ese than that but this is what it meant). Since wife and I didnt' want to sit on the Internet but only do quick checks having one device on at a time worked fine.
Question: is that how Princess wifi works?
Question: what about the the Medallion app? Does the wife need a wifi pkg to be able to message me, find me on the ship, order food to her chair side, etc?
