We had no excursion planned and were dropped at icy Strait from our Royal Caribbean cruise. The zip line I understand is the longest single run in the world and looks great. I was not with others willing to go so we watched. We took a quick bus into town and walked around a bit. Alaska is beautiful but not much to do other than look at the landscape. We found a great restaurant experience and walked back to the point. Not much there other than s souvenir mall. I would recommend an excursion of some sort unless you just want to relax. You could do the zipline and those that did loved it (no need to book through the cruiseline when we were there).
