Separate Whale Watching Tour

I'm trying to decide if my family should do a whale watching tour. We have done a whale watch sailing in the Atlantic from MA. We are cruising on Carnival Spirit with stops in Skagway, Juneau and Ketchikan. We are doing the Tracy Arm Fjord and Glacier Explorer excursion.

I have two questions, given the above information what would a separate whale watching tour give us and which port would be the best port to book a whale watch.

Thanks,

Love asking a question that someone posted while I'm typing the question.:o I don't know how to delete this post

You sound like you have little interest in a whale watch and am only considering it, because it is well recommended on this board??? Do YOU have any interest?? The only reason to go again. Never expect more than blows, backs and tails for sightings.
