Haines/Skagway Concerns

[travgurl]

We dock in Haines next summer at 6:30 a.m. We do not leave until 9:00 p.m. We want to do a 7 hour excursion in Skagway that we book independently. Do we have enough time to catch a ferry to Skagway, do the excursion and return? How do we get to the fast ferry in Haines once we get off the ship? Has anyone caught the ferry before, any problems? What do you suggest? Before booking the excursion I want to make sure and feel comfortable with all of the connections I have to make. Thanks!
