Julie, you will see a lot of families using the walkie talkies, of course lots of times everyone is using the same channel, so you get a lot of chatter on it.
I have a teenage daughter which I used to have to round her up for meal time, then we decided that we would set times and locations for her..If we have late dining, she is to be ready and in the dining room at the appointed time, if she does not show or is late, then she gets to spend the entire next day hanging out with mom and dad. If we have port plans and she doesnt show up at the designated time to disembark the ship, again, the next day she gets to spend the entire day with mom and dad. Its amazing how they can find out what time it is and be on time for meals etc, nothing worse than spending your cruise vacation with your parents.
Have a great cruise!
