This was my wife and my first cruise together. It was a great escape from our hectic lives and I (who normally love adventure vacationing where you arrive home completely exhausted) even loved it.
Celebrity provided a fantastic escape. We really did feel like celebrities so the name fits well. The staff are first class. The cruise had families on board, but it felt more like an adult cruise.
Our room was on the back of the ship on the bottom deck. The advantage of this location is that you get to see the ports as you sail away. Since this room was the last one near the corner, it was possible to see the whole rear view as well as part of the view off the port side. Downsides of the location are the constant hum of the azipods (360 degree articulating propeller pods), the fact that you can feel movement more since it is at the aft end of the ship, and that the room is a good distance from the elevators. The hum may have been a blessing in disguise though. Once you get used to it, it blocks out other noises.
We loved the room amenities. The bathroom was a nice size with a shower that even my 6'5", 210 lb frame was comfortable in. The TV options were more than adequate with lots of free on demand movies and shows. I love learning about how it all works and enjoyed the "about the ship" programs. The bed was very comfortable as was the couch. There was even space to get our luggage out of the way. The balcony was a great place to watch the sunset, view the ports retreating into the distance, and just relax.
