Like jrapps we were also on the Ovation last summer, and did Endicott Arm/Dawes Glacier. Once you hit the Inside Passage (I think maybe late on the first sea day?) there's beautiful scenery everywhere. I spent a fair amount of time during the week either in the Solarium or in 270 just watching the scenery go by. I couldn't believe how beautiful it was all day, every day, even through most of the evening because the sun sets so ridiculously late and comes up so early.
As for the morning where you do the glacier, I absolutely recommend getting up early. I know it's early, and it will be FREEZING. (Our week was unseasonably warm, and for most of the week I was in shorts and t-shirts- but that morning I was fully bundled with thick jacket, gloves, beanie, everything, and it was still a tad chilly.) But it was an amazingly beautiful sail to the glacier. We saw a bunch of seals hanging out on ice floes, water streaming down the hills on both sides, and just the most amazingly blue water. We watched pretty much all of it from our balcony, just ordered some room service breakfast and enjoyed it from there.
