I booked Celebrity Infinity .. similar ship .. Looking at the ships plan I booked Vista deck as this has just cabins above and below me and I thought should be quiet.
Any ship I go on I always look for the deck with this situation as long as it has a balcony ... Then I do not not have any surprises.
The cabin you mention on the plan is on Sky Deck
Have a great trip.
We were in 9047 on the port side almost opposite from where you are and did not have any problems other than the overhang from the Ocean Cafe immediately above which does limit your sunbathing out on the balcony. The noise we heard was sometimes in the afternoon the tables being moved about in the Ocean Cafe getting setup to do the casual dining option.
