Oh you will love the Mariner as well as Alaska! I wish we could go there every year because the beauty you see is just beyond words.
Karen is right about Hubbard Glacier - what a spectacular sight!!! :)
We did the White Pass train ride (Skagway) and the scenery from the train was so beautiful. Your itinerary shows Ketchikan on the Regent website...if you like eating crab and a small plane ride we did the flight seeing and crab feast at George Inlet lodge and it was out of this world!
Have a great time!!!
