We had two rooms under Cabanas (10120 and 10122) on our second cruise and several of the online reviews complained about noise from chairs above. But, although most of us are light sleepers, we never heard a thing and had a wonderful cruise. I think people are just different and have different tolerances for noticing stuff like that. In fact, every cabin, we've ever stayed in (10092, 10120, 10122, 10592, 12004, and 12012) was beneath a public area and had reviews with noise complaints, some even severe complaints. Still, we never noticed a thing in any of them. We did notice noise from the panel dividers on the verandahs on nights with high wind. Those were far more significant than anything from above could have been, but it's just part of the cruising experience. Personally, I would much rather stay on deck 10 than deck 9, but that's just because deck 10 has worked out so well for us that there's no reason to change it. In particular, the aft staterooms are nice because of the easy access to Cabanas.
