On our late July cruise this year, there were several families and I think the youngest child I saw was about 5, the only one that age. Most were 8-12 (guessing) and then some teenagers. The young one,6 or 7, on the White Pass RR was asleep. Personally I think 5 is too young to appreciate Alaska; 10-12 would be much better. The only noise I heard was from the pool one day, pretty chilly but they were enjoying.
