Normal
When in Alaska -- you want to spend time at the front of the ship, seeing what is about to come. The naturalists will be talking about things that they see from the bridge at the front of the ship and it will probably be gone by the time the back of the ship sees it. The ship will spend more time approaching a glacier with more viewing from the front of the ship and then it will turn around and quickly leave. So those with a front/top view will have more viewing time then those in the back because the ship will go slowly into the glacier and then quickly leave. Those in aft cabins on my last Alaskan cruise who didn't go out on deck only saw Marjorie glacier for about 10 minutes. Those with a front/side view and those on deck viewing the front got to see it for over an hour. I would never book an aft cabin in Alaska.
