Thank you all who had replied to this post, but a few follow up please.
To Howie or anyone who knows:
Skagway:
You mentioned taking a boat to Haines in Skagway. Will we have sufficient time if we have about 4 - 5 hours to spare? Is this guided tour or something we can do on our own? We're pretty tight on the budget.
Is the town of Skagway near where the ship is docked?
To everyone 
Victoria:
The Buchart gardens in Victoria sounds wonderful. Does anyone know if we could do it on our own? Does the ship dock close to the town? Any buses to take us to town if not too far?
Ketchikan:
Other than the free city tour, are there any trails or walks not too far away to do? We only have about 4 hours here. Can someone suggest what we can do in this short period of time, on our own. (spent all the playing money on heli-hike in Skagway and mining tour in Juneau)
To Alohagail or anyone who knows:
Juneau:
I'm happy to hear the mining tour was interesting for you. Were you guys on the Historic Juneau Goldmine tour (12:15-3:00pm)? It says.
... following a short ride to the site of the mine's ruins, your driver set the stage as you make your way through the rainforest and up Mt. Roberts..
Do we get lots of time to sightsee Mt. Roberts as well?
Thanks!!!
(9 more working day to cruising!!!)
