No children facilities on Azamara, and not encouraged on Seabourn or SilverSeas. The Saga cruise ships are entirely for the over 55 crowd. And 2 P&O ships [Artemis and Arcadia] are totally child free. Wish more lines would offer this option..
Thomson Calypso is child free, we had a great cruise on it this year.
Fred Olsen- have beeen 4 times and only met one 4 month old baby and no kid at all. It's very English though .....
