Did Alaska once on a Princess cruise. If I were to do it again, I would do it the same time of year I did it last time which was during the spring. Lots of animals and their offspring to see that time of year so I got some cool pics. Didn't hurt that I brought a 300mm f2.8 lens and 2x magnifier.
That said, I wouldn't ever do another cruise to Alaska. Sure, it's a beautiful place but I'd rather see it from shore and go more inland rather than take a ship again. I've taken at least 1 cruise a year for almost 20 years and prefer to stick to the warmer climates. The week we went to Alaska, it was unusually warm for that time of year. Everybody was comparing it to a typical Summer day but it was still too cold to fully enjoy a cruise ship IMHO.
