My wife and I are planning to do a round trip cruise to Alaska from Seattle this summer, and there are some differences in the itineraries. They all feature pretty much the same port stops, but the main difference is the where they cruise to view glaciers. From what I can glean from these boards and other sites, Glacier Bay is the best, followed by Hubbard, then the Tracy Arm. It sounds like they are all nice, and I wish there was more glacier viewing than port stops. Oh well...... Can some folks who have actually been to one or more of these areas chime in with an opinion? We are probably going to go on either Royal Carribean or one of the three Holland America ships that sail out of Seattle, so we have the ships pretty well chosen. Thanks for any input that you can give us!
