hi thinking of taking 7 day cruise , have three children 7, 9 & 10. I think for the kid's club the age break is 7 & under and 8 & up. I may be wrong. My 7 year old is very co-dependent and I know she would not "go alone" while her siblings stay together. Would they let her age up? Or would they let the 9 year old stay w/ the 7 year old? thanks for input.
