I would look into Skagway helo glacier landing in case the Juneau trip gets canceled. Several nice hiking trails if you are into that type of thing.
My suggestion would be to tell her at Christmas so she can read up on things to do, what to see and watch youtubes. Because of lots to do don't wait until the last minute for planning and have at least one backup plan for each stop. It seems like you are getting a good start.
