Basically, but it's not that bad. The way I remain flexible with this itinerary is, if we are going to ISP then I do whale watching in ISP. If not, then we do whale watching in Juneau. Between whale watching, the museum, and the hike, we can make a day of it. After multiple visits to ISP, though, we start looking at the Patter and checking to see if maybe some events on the ship are more interesting than getting off.
