The verandah was lovely. Spent a lot of time out there! It is the same depth as all the others (don't have a measurement, but there was plenty of room from the cabin door to the rail for the chairs (regular upright patio chairs). It was longer/wider, due to the cabin being larger. The floor inside had a slight upward slope to make the threshold level and accessible. If you stood at the rail and looked straight down, you saw the tops of the lifeboats, but sitting down, looking out, you saw the ocean and the horizon.
Will look for photos to post, but haven't had a chance yet.
We are cruising again this summer on the Fantasy, which is essentially the same. We asked for the same cabin because we loved it so much. Unfortunately, it wasn't available, so we are going with another accessible cabin on the other side of the ship, and I am sure it will be great as well.
