We did Alaska in a Cat 9 oceanview on Deck 2 and had a wonderful time. Did not feel the lack of a verandah made our cruise any less special at all.
Whose to say there won't be something exciting to see on the port side of the ship when your verandah is on the starboard side? So, the argument that you must have a verandah to see all that is going by doesn't hold water to me. We had friends and family in 6 cabins on the Deck 2 and we all had a great time. On Tracey Arm day we spent tons of time on Deck 4 which was virtually empty.
DCL provided blankets and we were dressed properly so very warm. We hung out by one of the doors that lead into Deck 4 so we kept cutting through the ship to catch the sites on either side of the ship. We had a wonderful time. We certainly don't feel having a verandah would have really made our trip any better.
