First time cruiser here! We are sailing to Alaska on Millenium on July 10 and we have cabin 8098. I read a post somewhere that it has a partially obstructed view. I called my travel agent and she said it doesn't and then she called Celebrity and they also said it does not. I'm still worried though so I hope someone can reassure me about it. Thanks so much!
We were on Summit in cabin 8042, forward of where you will be, and we didn't have an obstructed view at all.
You will be 2 decks below the Spa (?) deck - where the pools are - and it does hang over a bit in some areas, but you will not have any issues.
We were just on the Connie and had cabin 9032, and this did have a slight overhang for which we were glad as it provided a bit of cover from the sun. I guess if you wanted to stargaze at night it would be an issue, but not for us.
