We have sailed in an Aft stateroom 10 times on the Fantasy since 2012. We love these cabins because of the oversize balcony, with many of them more than double what you would get in a typical room. We are currently booked in 10158 on the Fantasy this coming Sept 2nd. Yes, the vibrations were somewhat worse prior to some of the fixes... but for us, it was not a problem. If the stabilizers are used, it got worse but it was not constant and on some cruises, not even noticeable. We had a cruise in Jan this year and felt nothing unusual. BUT, if you think you are possibly sensitive to the issue, I would not stay in the Aft cabins. Deck 10 has some noise early in the morning if there is movement of the chairs on the deck from Cabanas but not a problem for us. Never stayed lower than deck 8 so not sure about the clubs. We have also been in cabin 9670 which was amazing. That room is I think more than double the size of a typical room. Balcony was massive, like we could play hockey out there...
