Here is what my Soulmate and I did a number of years ago (the interesting thing was the RCL agent convinced us out of a 14 day north/south B2B on Radiance to do this instead):
1). Fly to Vancouver and take the North Bound cruise to Seward. Make sure you get a Starboard Balcony (do not miss the Inside Passage ... I thought I could touch the tress on the shoreline).
2). Make sure the itinerary has the Hubbard Glasier ... it is stunning. We enjoyed tons more on the cruise, but many people have already covered. Hubbard was the highlight of the cruise.
3). Do a land tour (we did ours self directed, but a tour group would be fine as well). Do not miss:
Denali ... We had two views of the spectacular mountain: Talkeetna and from Denali National Park.
Talkeetna ... a great town to visit. If you are there on a Sunday morning there is a cafe that only plays the Beatles (we stayed there for a couple of hours (breakfast and a break)).
Denali National Park ... we had a 13 hour bus tour. It was "other worldly".
Anchorage ... lots of history and things to do there.
Alaska ... was one of the most welcoming places we have ever visited. We thought it was once in a lifetime visit. Nope ... we will go back.
Bore Tide Surfing on Turnagain Arm ... We did not do it, but it was fun to watch.
Obviously, there are more things to do, but we only had 6 days.
4) Fly back out of Anchorage
The RCL agent (who was from Alaska) said the North and South itineraries were pretty much the same. She said, "do not go all that way and miss Denali".
Hope you have a blast,
Curt from Canada
