I have never been on a cruise before and when I booked, the category is outside cabin with "possible" obstructed view. Of course, I should have realized that this pretty much means obstruted. Plus, I've heard other people say that it isnt so bad and that there is plenty of light that comes into the room.
My girlfriend went with her husband, so I guess she felt safe enough. She did say after about two days she was able to close the door!
