Minnie is right!!!
I know that this is the DIS board, but, honestly, when I saw the itinerary of the Disney Alaska Cruise... No way I would choose that one.
No Glacier Bay... or other great sights...
I would love to take an Alaskan Cruise one day!!!
(Unfortunately, with airfare from here in the south to add on, it is pretty prohibitive on our budget)
I have done a little research...
And, I know exactly which cruise I would choose....
Princess Cruises...
The Coral Princess on the Whittier to Vancouver itinerary.
It is one of the very few, if not the ONLY, one that stops at both Glacier Bay - AND - Hubbard Glacier.
Two of the most magnificent sights!
It is supposed to be an excellent ship and an excellent itinerary.
Now, for something simpler, you could choose a Princess round-trip from Seattle... I think they would get Glacier Bay on that one.
If that would be enough 'Alaska' on that limited itinerary, you could consider that.
But, IMHO, the one-way itineraries are where you really get to see what you go to Alaska for.
And, the previous poster is right...
The other option would be Holland America.
They probably have some pretty good itineraries too.
If you see a good itinerary, and are choosing by which Cruise Line would be more to their taste... Then look up cruise reviews and especially good photos of the ships... Note that by all accounts, that Holland America is considered the 'old folks' cruise. (floating nursing home... Hahahah!!!)
I would NOT consider a NCL cruise to Alaska.
Personally, I would consider the
Royal Caribbean Radiance of the Seas.
That would probably fit my younger tastes.
But, again, as Minnie just posted, the itinerary is limited compared to what Princess or Holland America can offer.
For your parents.
I agree with the above poster.
Go look at Princess and Holland America...
See what they have to offer...
Choose from there.
Hope this helps!
