Hi Mama Tene
I was in #8610. How much sun depends on the ship orientation(heading). The balconies are open(they include 'hard plastic' chairs and table. The first thing that I did was ask the steward to replace with lounge chairs). I felt no vibration here. In fact, I never knew when this ship docked. I wakeup, open the curtains and see people getting off for their excursions). I always prefer upper decks and about 1/3 up from AFT (and away from the elevators(passenger traffic and noise).
