My wife and I (both in our mid-late 50, she more "mid" than I) sailed on the fall foliage cruise late September 2005. This was our third Celebrity cruise, although we also took two Chandris cruises in the early '90s. The ship is in fine condition -- we couldn't find a single area of uncleanliness or deterioration. Early every morning I would go for a long walk and encounter multiple crew members scrubbing something or other.
We booked a Sky Suite (#8117), the second cabin from the central elevators. It was a regular (non-handicapped) room, and we were amazed how much space we had. We took seven bags to the ship and had space for everything! That was a first for us!
Suites come with butler service but I'm not sure what the advantage is over what the steward does in a regular room. Our butler did everything "by the book" and, as a result, seemed rather bland by being so professional. Butlers we have had in the past were much more personable and thus more enjoyable. This is not to say that this butler was bad, just not memorable by not letting his hair down a little.
