I just came off the Getaway. What you describe (including needs for children's activities) sounds like it would be met with a Haven suite mixed with regular ship activities for the children.

I've previously cruised on Seabourn and would rate what I saw in my visits to the Haven (I didn't stay there but your friends did) at that level, minus the all-inclusive you'll get on the true luxe lines. Haven folks still have to scan their cards all the time.

Seabourn is lovely for adults, but nothing special is there for kids. Just as well for me - after having 1,500 children on last week's cruise, I long to a return to an adults only cruise!!!
