In January (2015) my family had the pleasure of staying in cabin 8602 on the Disney Magic. This is an handicap accessible aft one-bedroom concierge cabin. To say it had a large balcony/verandah is an understatement.
This verandah has no protection from the sun and is visible from cabanas above. The lack of sun protection was not ideal for my pale husband and son, but we still really enjoyed that balcony.
There will be more on this cabin and sailing concierge on Disney Cruise Line at some point in the future!
