I've got to say that, this being my 5th cruise with Celebrity and 12th overall, that this was the most underwhelmed I've ever been on a Celebrity ship. I took Solstice a few years ago, and loved it - seems like the changes in Reflection to accommodate the suite class guests has diminished the experience for everyone.

Embarkation was extremely easy and organized. Got to the port on my Embassy Suites shuttle and boarded within 10 minutes.
Good cabin - nice layout. Minimal noise and near the elevators.
