I know what you mean because my dd and my 2 sons are tall and look older than they really are - especially dd! There were times I worried about CM's thinking I was lying about their ages but I knew I had truth on my side (as well as a copy of their birth certificates in my luggage just to ease my nerves) but nobody ever said a word. Except the gentlemen that got into the hot tub with my 14 year old (actually was 2 weeks shy of her 14th birthday) at the Swan and struck up conversation with my dd asking where she was from and she was they guessed 21 right? NOT! My ds who is only 11 knew to say, "Come on sis, dad said we could only stay in here for a few minutes" and they got out.
