Queen, this is the kids area, on the Eclipse. Between RCI & Celebrity, I would honestly say, RCI would give you the better childrens fun experience onboard. The demographic Celebrity wants, is not geared to families, and, since RCI is all about families, better facilities with a long background in making kids happy is a plus.
The kids I remember on HAL were older,and seemed to be wandering around looking for fun,and seemed bored..glad your kids enjoyed themselves.
On the old Westerdam, we had a livlier night life, but still more quiet then other lines we have sailed. Our Z cruise, really was an odd one, glad that we have ever experienced that again. I thought she was a beautiful ship.
