On Explorer of the Seas you could view the Bridge, which is fully enclosed of course, through a window on one of the upper decks. The man in the picture is looking at a diagram showing the locations of all the equipment. It doesn’t show up all that well in my photo but you can see beyond to the fore deck below.
This has to be nicest view from a toilet I’ve ever seen.
You can’t see through this window as it has reflective glass but this is one of my favourite window pictures.
