An 11 day itinerary in the 'sun' (it actually rained a lot, but was warm) was the attraction. 4 x sea days (2 at each end) plus 6 ports (we'd only been to one of them before) looked good.
The voyage and ship did not disappoint. I really like the ship's layout - particularly the 'lawn' on Deck 14, aft.. The staff and crew - led by "Captain Kate" - were very forthcoming and entertaining. Very visible. Did not hesitate to talk to you if you saw them around.
I really think that Celebrity's food is above average. We cruised RCI two months ago, no comparison. Also, we had a dedicated sommelier for our section; he was great. Kept the glasses filled (often with wines that weren't on our "Classic" packag).
