I had a scenic oceanview on the Freedom (deck 9, Lido) at the center. The view is amazing and because the window is slanted out you get a little table and chairs for a nice sitting area.
The guidance on closing the blinds at night is that you must close them if you turn your room lights on. We left our blinds open every night.
Noise. Yes, at 6am every day (except the last day) there was a loud rhythmic, unexplainable noise that would last several seconds, stop, then continue for 2-3 minutes. Some believe it is window washing system for the bridge which was immediately below our room.
