We have stayed in 4E cabins several times and love it. There is an overhang on the veranda which is where we usually sat so we weren't in direct sunlight so I doubt anyone looking down would see us. When we did sit or stand by the railing and looked up, we could see people above us only if they were standing at the railing. If you are sitting on your veranda I doubt you would see anyone below you. As for noise, it's unlikely you would hear anything from deck 5 if you are on 9. The most noise we heard was the wonderful sound of the ocean!
