Shore excursions on Silver Muse Alaska cruise

We have decided to do the Alaska cruise on Silver Muse, and would appreciate recommendations on outside private tours for shore excursions at the following ports please:-

1) Ketchikan

2) Juneau

3) Skagway

4) Sitka

5) Seward

Recommendations on both tour operators at these towns as well as recommendations on what excursions to take would be much appreciated.

Thank you.
