I don't see anybody here who is pushing ONLY Disney cruises.
And, there has been a lot of good info.
Tchan, I had also sent you a PM about my experiences with cruising.
And I recommeded a line other than
DCL.
Extra staff or so-called activities or not.... Princess is just NOT outfitted with the space and the infrastructure (kids areas, slides, etc...) for families with kids. They just are not. The very idea of more than two adults in a tiny (smallest in the industry) cabin... that alone is a factor.
Since Princess is HUGE in Alaska, and some of the best itineraries in Alaska, we considered an Alaskan cruise on Princess. When researching, like on Cruise Critic, I can remember, very specifically, comments like the ones you are getting here, regarding kids on Princess.
Their limited efforts on having a kids program was a lot of coloring and 'learning'... (coloring, talks/lectures) like about glaciers and whales, etc... Almost sounded 'academic'.
Tchan, you will just simply not find any fun-factor onboard a Princess ship.
