The inside passage cruises round-trip from Seattle which is convenient because you don’t have to do a pre/post night and you don’t have to have a passport. The inside passage makes stops in Skagway, Ketchikan, Juneau, and usually a night stop in Victoria. It also includes one day seeing a glacier from the ship either Glacier bay, or Tracy Arm my favorite being Glacier Bay where you feel like you are right in the middle of the glacier.
In my opinion none of the main cruise lines do a better job of cruising the inside passage than Princess does. They add extra touches that are special just for Alaska. Which includes having naturalists on board, seminars about Alaska,and special tours because they partner with Animal planet and Discovery, Alaskan food, and a new favorite of mine: puppies!
In the piazza where they bring Alaska sled dog puppies on to the ship and yes you can hold them.
Also, if you have anybody in your family/party who loves crab the restaurant at the top of Mount Roberts Tram offers an all you eat crab plate for $62.00 that includes sides, Crab bib and bucket. Delicious!
I would be happy to help you with any of your Alaska cruise requests either email or give me a call.
