You probably know better than most people, how much I love Disney...especially
DCL. And it wasn't necessarily an easy choice for me to go to Alaska on Norwegian. But we really, really wanted to do it this past summer, and I'd gotten to the point where I was afraid DCL was never going to take us.
Let me make something
very clear upfront. I am not in any way condemning anyone's choice of another line. You don't need to defend it. I just find it amusing that this is going on on a DCL forum. People keep going on how the other lines are better but then come back here. I don't think that any line,
including DCL IS better, it's what works for you.

Each and every one of them have their own style, are any of them truly 'better'? Not from my point of view. Each and every one of them have pluses right alongside caveats, you're giving up something to gain something.
But here are the honest truths:
You're right, it will still be BEAUTIFUL ALASKA no matter what ship you're on, regardless of one glacier or another....but there's another port missing on DCL, too. So, dollar for dollar only....the other lines are a better bargain.
Maybe on the less ports, but *shrug* there are, as you already well know, a lot of values I put a high price on over other lines. It's more than the number of ports. Read on.
NO...they don't have that Disney "magic", and yes, I always find myself comparing these other ships to DCL, no matter what. I LOVE DCL.
But again, sometimes, the other ships do come out on the PLUS side. Money saved is a huge plus. The extra things for our older teens (bowling, rock climbing, onboard activities) were a huge plus.
You bring up that 'magic', that magic includes things like we don't have to plan >zero< once we set foot on that ship. The all inclusiveness that they put together is of great value to us. Things like a dinner waitstaff that knows exactly how to serve us by the second night is a big value. I adore the rotational dining, and even after umpteen cruises still love the theme of each restaurant, it doesn't get old for us. Those commercials that try to make out the preplanned structure as some
horrible thing are pretty darn funny to me. I know I'm paying extra for all that upfront and enjoy the service.
Bottom line....I was never sure I even wanted to go to Alaska, but it was something my husband wanted to do. I found out once I was there, that I could go back again and again and again. I am definitely more of a beach person, but the beauty and serenity and the clean air (and I could go on and on) of Alaska really got under my skin.
And I'm looking forward to this trip for those reasons. And the people being so negative about what DCL's doing
now simply don't understand that this is what they had to work with. Alaska has very aggressive limits that DCL had to work within, they only allow so many berthings at the 'big name' places, period. They are the new kid on the block, and don't get the first choices. And I'm content with that, knowing that if this does prove to go well for them, they in the future, will pursue other itineraries and gain those other locations. And I'll still get to see glorious Alaska.
Which cruise line would I choose? Well, honestly....it depends on the money and what I felt my needs were. If I wanted a suite at the same price as a DCL Cat 4 or 5....then it would have to be another line. If I wanted to see Victoria and Glacier Bay....then it would have to be another line. If I didn't want to fly in and out of Vancouver (been there, done that) then it would have to be another line.
There, you and I are in totally different places. We sail in the Navigator's Verandah by choice, not because of its price point, have no desire whatsoever for a suite.
And my viewpoint of going on vacation is to go on vacation. I'm going to have some downtime, that is going to be quality time with my wife, and have a good sampling of destinations while aboard that ship. That's it. When I get back home I'll appreciate that experience and return to the rest of my life happily, usually eagerly, and hopefully well rested. Going to that 'name' destination or not has pretty much no meaning, Glacier Bay, Tracey Arm, wherever, it has glaciers.
And in that vacation, both the destinations and the ship itself have to be considered equally, I can't compartmentalize one over the other, if I'm not comfortable with one part of the trip, the rest is going to suffer for it.
Also, am VERY looking forward to visiting Vancouver, we are treating it as a destination of the trip, not just a pass through point to the ship. Have a day trip planned to the Victoria(Butchart) Gardens and everything.
BUT....if I am DYING for my Disney fix....then it would obviously have to be DCL. And I'm honestly hoping that one day in the future, I CAN go to Alaska with DCL....if for no other reason than to be able to honestly compare. Well, and the fact that I'd go back to Alaska in a heartbeat, anyway.
It's not a Disney fix so much as a DCL fix.

And yes, can always go back some other time.
