No one seems to have answered in the negative yet. ... And I won’t, either.
Four cruises to Alaska. Only the first one on Disney. The rest on Princess. Booked on Celebrity for last May, but pre-COVID had actually already changed it to Disney Magic out of San Juan to see a new place and complete my nephew-in-law’s Grand Slam (he is such a newbie).
I find the ship less important on port-intensive cruises - especially when those ports are spectacular.
Now, if your kids (or your budget) don’t enjoy trains, planes, helicopters, dog sleds, kayaking, hiking, biking, whale watching, then Alaska might not be the place for you. Yes, the ports are small towns. That is some of their charm - especially Skagway, the starting point for many who traveled into the Yukon for the Gold Rush. Most Caribbean cruises pull into small town ports, too. I guess the Med does, too.
We saved money on our DCL cruise by staying in sideways inside cabins on Deck 5 or 6. Single bathrooms, lots of floor space. You can put all the kids in an inside and get a balcony for the adults.
I recommend saving on the cabin because the port adventures are not cheap, but those great adventures can really make Alaska cruises the stars they are (after a few cruises, I really just cruise to see the sights; I always visit Mendenhall Glacier in Juneau to see how much it is receding and enjoy it while it is still there).
Whenever I get the opportunity to include Glacier Bay or College Fjord (with its 16 glaciers), I book that cruise.
Our family joke about cruising to Alaska comes from deciding whether or not to do an onboard booking at the end of the
Disney cruise. My reply was that no one needs to do a (Disney) cruise to Alaska two years in a row.” I have to remind my sister that I said “Disney“ cruise to Alaska. The next year it was Princess.
Disney is great for kids, though. We didn’t take my nieces on other lines (other than one kid to Alaska - and then she chose Disney to Alaska for her honeymoon six years after her first visit).
