Trzgoa and AF, welcome to cruise-chat.
We took the Alaskan cruise/landtour in 2008. In Skagway we did the White Pass Railway, taking the train up and a bus back down. In Juneau we took a floatplane to Taku Glacier Lodge. It was a great excursion and we plan to do it again someday.
Alaska is so awesome. You'll love it!
