We've been on multiple ships with Disney, Royal and Celebrity and have never had a bridge viewing room. We have paid for "Behind The Scenes" tours that took us to the bridge, engine control room, backstage at the theatre, a galley or two, food storage areas and even a crew bar. The cost was usually between $100 and $150 per person depending on ship. Royal did allow photos in all of the areas, even the bridge, but that was about 10 years ago, so things may have changed. Celebrity also offers a ship's art tour on the Edge class ships.
