I had not sailed with Celebrity for over a decade and we chose this trip as we were able to stay overnight in a couple ports on the way and liked the overall itinerary.
First off, I read the above review of the people in 9156 (the folks with the bed bugs) and I have to say that freaked me out as we were in cabin 9154, just around the corner. We did not experience any issues with bed bugs; but that may explain why there was so much crew noise outside our cabin. The cabin stewards also set up their station outside our room so it was not truly quiet that often.
The ship did look a little dated and there was nothing about the decor that really stood out - the Millenium is really lacking in any type of "wow" factor.
Noisy room - stewards stationw as right outside - cabin around the corner reportedly had bed bugs.
