Thanks finadict. There is a member who pm'd me that runs a boat out of Gustavus. They specialize in 5-day inlcusive tours, but he suggested that they are not fully booked all summer and may be able to do a day trip.
We are going to do a family whale watch tour in Juneau, followed by a visit to Mendenhall Glacier and if there is time we may go up the Mt. Roberts Tram. In Skagway, I have a car rented and we are going to drive up to the Emerald Lake area. I found a mile by mile narrative at
www.murraysguide.com. The scenery looks awesome. We have not decided what to do while at Icey Point, but I wouldn't mind wetting a line. The only downside is there may not be much for my wife and daughter to do. We'll see how it works out. If I don't get to fish it would be OK. Coming from Central Florida it will be great just being there.
