Did an Alaska cruise a few years ago, it was very enjoyable. Took Holland America, great experience and very few, almost no kids.
Do you remember what time of year?
Second that message! Great time with Holland America (they own the Alaska/Denali resorts!) with 3 nights in Denali and great outings, plus the slow train (on purpose for scenery) to the dock for the 7 night HA inside passage cruise with glaciers and beautiful sights! Highly recommend and look forward to going again in 3 years... ymmv (send me a PM if you have more questions)
