It was our first time on Celebrity and we wish we hadn't left it so long. We have had a couple of disasters, mostly on the cheaper ships so you get what you pay for. But we got fantastic value for money on Reflection.
The ship was beautiful and well maintained and the atrium was good fun. But it was difficult to find a quiet spot away from music completely, reminding me a bit of Carnival. However that was not an issue for us although it may be for some.
The size of the stateroom and shower was also a pleasant surprise. Big enough for my not insubstantial frame for fitting into.
Spacious, big shower, sufficient storage space but some a little awkward to reach above the beds.
