Ocean Atlantic Cabin Question

[GPS]

We are trying to decide between cabin 701 which is the only stateroom on deck 7 of this ship vs one of the similar cabins on deck 8 for an Antarctica cruise.  The expedition company has told me there is no difference in size, but they seem to think cabin 701 will have more deck access due to its location, but has a partially obstructed window view with a gangway outside.  I'm wondering if anyone has actually sailed on Ocean Atlantic in the 701 or 800 cabins and can advise which would be more preferable for privacy and access to outside decks.  Thanks.
