Many cabins are obstructed on Deck 9 -- most are partial, but range from about 5% to 80%. The obstructions are due to lifeboats, so you will still get some light. Are you looking at the suites or outside cabins? I have a list of obstruction percentage of the suites, but could probably get my hands on the status of other cabins. We recently stayed on this deck, and previously stayed in a fully obstructed cabin one deck below.
