We were there the middle of July - we took the Princess roundtrip San Francisco cruise through the inside passage. Can't say that I "saw" Alaska, but I did see a very pretty part of it, along with those awesome whales. We went into Ketchikan, Juneau and Skagway. I enjoyed getting to visit the places that I had read about in Michener's "Alaska", especially Skagway.
Someday I'd like to take a trip through Denali National Park...then I will feel like I can actually say that I've "seen" Alaska.
