Have a word with the youth crew when you get on board. I dont specifically know for this ship but generally they tend to be most accommodating. You'll probably find that the boys soon team up with lots of friends! have a good cruise David Powell travel journalist.
We too are on the same sailing with two boys aged 11 and 13 i.e different clubs. Two years ago on the Jewel they said they had to go in their own clubs. It wasn't a problem and they met up with two boys from Boston (USA) and email them. I will tell them to look out for your boys.
Hi, also sailing the same date, I have been before(2x) they are quite strict but if you talk to the cruise director which I did, it worked and both kids went to same age group. wish you luck and see you on board. Ian.
