We recently returned from 7 days on the Westerdam. There were a lot more younger people than I expected. We didn't mind it, but I thought the entertainment was lacking, especially for younger folks. There weren't as many venues as on some of the other cruiselines we've been on, and we didn't care much for the entertainers on this particular cruise. If I was bringing kids, I'd pick Princess or NCL over Holland. I think they'd be more to keep them entertained.
