I'm 13 and I'm going on a Royal Carribean cruise in April for spring break and my 16 year old cousin is going with me(he's more of a brother) The age groups are 12-14 and 15-17. I wouldnt be with him. I am a very mature 13 year old and dont even look my age. Is there anyway they would let me go in a group with the older kids as long as my cousin is there to protect and watch me?
