The video posted by thebutlerdidit indicates to me not much difference in the views along the bank of Sky Suites on Deck 6. We are booked in one and not concerned at all about the lifeboats below. The commanding view is out to the sea not down. The Sky Suites on 8 and 9 would not be preferred for us because they are very near the panoramic glass elevators possibly sacrificing one’s privacy on their verandah.
Also, regarding Aqua on Deck 9, don’t forget about the echoey metal overhanging Deck 10 above you. It’s not the noise from Deck 10 that would concern me. We never heard anyone or anything coming from Deck 10 above us. Rather the issue for me was the cantankerous metal supports holding up the overhanging Deck 10 and disrupting the view. The shade was nice, but the overhang and metal supports created a less than premium aesthetic while enjoying the verandah. Voices from neighboring verandahs carried. Lifeboats over this for us.
