As promised, I'm posting my thoughts on the Juneau salmon bake... SUPERB! We did this as part of a larger tour (booked through HAL) that included Mendenhall Glacier. When we arrived at the salmon bake, we started with delicious chowder, followed by a buffet that included cole slaw, rice, baked beans, and cornbread. There was pie for dessert, and lemonade, water, coffee and tea to drink. Beer was available for a fee. We took the walk Gary suggested and it was wonderful. The stream was filled with salmon (it was spawning season).
We also loved Mendenhall Glacier. We were there for about 75 minutes, and that was enough time to walk a short trail for lots of photos and to view the visitors center. The glacier is impressive. While waiting to board the bus back to the ship, we saw a couple of baby bears and their Mama in the woods.
As for our other tours -- I agree with billybuzzy on the White Pass/Yukon tour -- it was our favorite. In Ketchikan, we took the Misty Fjords and Wilderness Explorer boat ride. We didn't have much luck seeing wildlife, just a few bald eagles, yet we really lucked out with the weather and were therefore had tremendous views of the incredible scenery there.
