We cruised on Navigator's inagural season in Alaska on July,2000. There were no kids, except an adorable little girl, but that was before the creation of the "Mariner's club" and catering to families with kids. It was a 10 days cruise and we loved it. We also cruised on Navigator for 14 days on the Iceland/ Norwegian fjords (NINJA) cruise which is to this day my favorite.

As long as the the dining experience is satisfactory, I don't have a problem going every night to the same venue. But of course, you also have La Verandah in the evenings to break the monotony.
