Our two week itinerary included
Glacier Bay visited twice
College Fjord
Hubbard Glacier
First stop Ketchikan we did the "duck" amphibian? vehicle for water and land tour around town. Lots history and good overview to where walks would take you. Second visit we did the lumberjack show and had a lovely walk around town
Juneau we did the Allen family whale watching and wild life cruise. Exceptionally good. Whale sightings guaranteed or you get $100 each refund. Gorgeous scenery everywhere. Second visit we did the Mendenhall glacier and Nugget Falls excursion. Spectacular.
Skagway we did the White Pass Railway. Beyond spectacular with all the snow. Stunning scenery. Our second excursion from Skagway was to the Kroschel Wildlife Refuge (Haines/Chilcoot). About 40 minute drive so plenty scenery to be seen. The most entertaining, quirky, amazing day. Steve Kroschel is such a character, a totally unique setting, NOTHING like any wildlife refuge we have ever been to.
Also Princess had exceptional rangers on board while cruising the glaciers etc with commentary, pointing out all sorts of features (eg a caribou being changed by a bear along the shoreline) a good pair of binoculars are worth every cent!
Hope some of this info gives you an idea of the adventure awaiting you.
