First time in Europe and with Celebrity. Sailed RCI, Carnival and Norwegian.
The ship was in great shape, well designed never felt congested and any line was fairly short. I really liked the indoor solarium pool it was a good size and had two 'warm tubs' in the adults only area, although there were almost no kids on this cruise, it was mostly a gray hair tour :)
The staff were excellent, the main dinning room food was very good and the specialty dinning was excellent. I recommend the 3 restaurant package tour. If you only do one , make it Murano.
Best cabin I've had, big balcony lots of storage, well designed. this Location is ideal, away from the elevators right in the middle of ship.
