We have sailed on almost every Celebrity ship in the fleet except for the Century and the newest Solstice class ship. The Millennium we have sailed on previously and the ship has been upgraded since our last experience. The addition of the Aquaclass staterooms on the stern of the ship added about 200 more passengers to the original 1950 passengers it was originally designed for. I'm not wild about the location of those cabins as they seem like an afterthought which they were. I would never book a cruise on Celebrity without it being at least an Aquaclass cabin. And the only reason for this is for the BLU restaurant which is open only to Aquaclass passengers for breakfast and dinner. i hate the main dining room due to the hectic nature of it. However the BLU restaurant on this cruise was a disappointment. We have never dined in the BLU on other than a Solstice class ship until this cruise. The service was slow and the food that was supposed to be hot, wasn't. I think this is due to having to get the food from the main kitchen rather than having a kitchen to themselves like the Solstice class ships do.
As far as the cabin goes, it's too bad the deck plan doesn't show what really is across the passageway from your cabin door (it only shows inside cabins). Directly across from our Aquaclass cabin door on deck 9 (cabin 9065) was a workspace for the cabin stewards and other miscellaneous people. So at 6AM EVERY MORNING it sounded like tin baking pans being slammed around along with loud talking by the crew. This went on for quite some time. It would have been nice to have known that cleaning space was directly across from our room so we really could sleep in a little more.
The cruise itself was nice and one of the highlights was being able to be a guest at the Captain's table in the main dining room one night with a different menu from the noral dining room fare.
We stopped at St. Maarteen, St. Thomas, Tortola, and Bermuda (overnight) on the way to Cape Liberty,New Jersey (10 miles from downtown NYC). The next cruise starts the 3 month round trip from Cape Liberty to Bermuda that lasts all summer for this ship.
