We will be going on our first Alaska cruise in June. I have been doing some research on shore excursions in our ports of call (Skagway, Ketchickan, Juneau and Victoria). Unfortunately, we need to keep the costs of this trip low, so some of the fabulous shore excursions are not in our budget. I have been considering renting a car at some, if not all, of the ports in Alaska and checking out the sights on our own. I would really appreciate any input from those who have done this. ...or those who enjoyed some of the less expensive excursions.
