What's the best way to communicate with others on a cruise ship?
Suppose I am on a cruise with my family. We sometimes split up and are on separate areas of the large ship. What's the best way for us to get in touch with each other? As far as I am aware, there is no cell service while we are on the Royal Caribbean ship. We do NOT need to communicate with people on the shore, just on the ship. Any tips?
Current contender: FRS radio. I'd prefer a way to text, but what all is possible?
