we did an Alaskan cruise with Norwegian a few years ago, had lots of fun. Just make sure your room isn't 3 floors up directly over the nightly entertainment or you'll get the music booming through your room. (Although they didn't go too late). I really enjoyed the train ride in Skagway, up along the old gold rush trail. Beautiful scenery. The old cemetery also looked interesting but just saw it in passing. Our tour went from Vancouver, south to north and then looped back. I almost wish we had done 7 days out and flown back, or started north and headed down rather than doing a loop. Didn't get as far north as Sitka, that sounds interesting. The nice thing about Norwegian is that they were one of the only ships to dock near Wrangell, so it was much less busy and touristy, got to walk around town and visit with the locals, interesting little museum. Stopped at Ketchikam, Juneau, Skagway and Wrangell. Ketchikam was very busy and touristy but good history, interesting heritage center. Did the gold mine tour at Juneau, there were only 3 of us on the tour since everyone else went whale watching, so we got a great personal tour and my young son got to see all the heavy equipment he ever wanted! Great food on the ship, no set time or place to eat, which meant you didn't have to be in the dining room at a set time at a set table. The draw back was that on the last night, when everyone wanted to eat in the dining room, the line up was out the door and up the stairs, we ended up at the more casual buffet. But, the chocolate buffet was pretty good!
