On our first cruise last year, we were told to buy radios to take, to keep up with our teen boys. We used them actually two days.
Pros: They do help you keep up.
Good way to remind kids of something they need to do, or a time to meet.
Cons: Hubby last year said"Please meet us on the Lido for lunch" Because he didn't call the boys by name, ten kids showed up to eat.
You are sharing air space with others. Depending on the ship, the radios wouldn't work in some areas. I was told that it was because of the steel in the walls. You tend to want to turn them off, because some people (old and young) use them to entertain those around them. We heard what sounded like an elderly man sing "Help me make it through the night" to his elderly wife.
It was cute, and painful all the same time. He sounded like he put so much in the song, that he had little energy for once they found each other.
Others to follow may say that they couldn't do without them. Maybe you have a better system than we did.
So, what do you think Cruisemates?
