One such cabin comes to mind. On the Carnival Spirit, there are some balcony cabins with obstructed views that you could get for a reduced rate, and the view really isn't that obstructed. The specific cabin I am thinking of however, has an extra large balcony, but doen't cost extra. There are a few such staterooms on the ship, but the one I sayed in was #6232. If you look at the deck plans of the ship, you can see that the balcony is twice the size of the rest. It was a very enjoyable part of our cruise.
