RellingTwin...tell your inlaws that they will absolutely love the Alaska Cruise..we spent a week in Washington state, cruised on Holland America from Vancouver, BC to Seward, AK stopping at Sitka, Ketchikan, Juneau, Valdez and then did the land portion from Anchorage to Fairbanks (via rail) and in route, we spent two nights in Denali. If they have any questions, you can just ask away!! It was the trip of a lifetime..the cruise through the glaciers was spectacular (although Sarah didn't appreciate the beauty..she told us she would catch a look on the videotape..so much for trying to show her the beauty of Alaska!!)
Even had a real bear encounter at Mendenhall Glacier--love to tell that story but Sarah won't let me because I embarrase her!! Also ran into a homeless person living under a tree in Sitka and when I pointed him out to DH and DD, they looked at me like I had 3 heads. On the way back to the ship, I was determined to prove that I was not looney..threw a few granola bars in reach of the bush and sure enough, the homeless guy came out to get them..he had an entire apartment under that bush!! LOL!!
