As this is half term there will be loads of children, I suggest you join the Roll Call.
How do you join Roll Call?
You go to site called boards dot cruise critic dot com. This is where you find the roll calls for all cruises. You have to register - it is free. If over 25 register then RCI throw you a party called Meet and Mingle. I have just checked and there seem to be 6 families all with children 'chatting' on there already incl one family with 17yr old son.
