What excursions should I do on my Alaskan cruise?

My husband and I have decided to join my parents and their friends on an Alaskan cruise. I’ve been going through all the various excursions, so many, and I am trying to narrow down what to do. The only one I know I am doing for sure is a trainride in Skagway.

Also possible in Skagway:

Should I do an excursion to a mushers camp? They tell you about what they do, you can play with the puppies, and they take you on a sled ride on grass, not snow.

Another one we are thinking about is horseback riding in Skagway.

In Juneau I have narrowed it to:

Floating down the river near Mendenhall Glacier. It is a 12 person raft, the rapids are not fast, barely rapids from what I understand.

Mendhall Glacier and Gardens. It’s a walking tour.

My parents are doing Gold panning and Alaskan Salmon bake, but I wasn’t sure I would enjoy the gold panning? I can do just a Salmon bake for dinner which I am considering. What do you think?

In Ketchikan:

A jeep and canoe safari. We drive the jeep through the Tongass National Forest and then the Canoe is a 20 person canoe, but it says paddle across the lake system, which to me means it might be just a short trip across to another side?

My husband leans towards a fishermans tour where we would be onboard one of the vessels that was featured on the show Deadliest Catch, but this is not a wild ride on the seas, it is calm and they tell you stories, and it it is scenic.

Last choice there is a land sea choice, walk around Katchikan learn the history, stroll through the rainforest then board a boat and hope to spot some wildlife.

What do you think? I am interested in comments from those who have been to Alaskan and who haven’t.
