We just returned from the September 1-12 Galaxy NE/Canada cruise, and I hope they do some interior refurbishing and major cleaning while the ship is in drydock. There was worn, stained upholstery and carpeting all over, and other evidence of wear. The arm on the seat in our stateroom was worn down to wood and stuffing, for example. Our shower came apart (in midshower, of course) and we heard of other assorted plumbing problems.
Friends with us who had sailed on Galaxy in January said that was not the case then, and since you didn't see problems in July, there must have been some rough trips since! The crew worked hard to keep everything as clean as possible, but some heavy duty work is needed now.
