Thanks again everyone for your input. However, in looking at prices, I don't think I can afford a balcony, so I'll just have to book an inside room, then go to one of the lounges or open decks early for the glacier day.
As it stands now, I'm planning on either NCL or Princess for the last week in August. This is one cruise though where I'll fly out the day before, and spend the night, as for me, this would be a cross country flight. I actually used to live in the Seattle area, so I may do some sightseeing the day before and after the cruise.
