Definitely depends on the size of your party. We were a group of five, split between three cabins on different floors of the ship. With how tremendously huge modern cruise liners are and how crowded cruises can be, I found it was invaluable. For example, being able to quickly message "I went back to the cabin" or "I'm on deck 6 at the table at the far back" or "meet you at the dining hall at 5pm" was very helpful.
