Having cruised a number of times with RCCL (on Brilliance & Navigator), and with Cunard QM2 once, my husband and I were keen to check out Celebrity Cruises.
Based on their marketing blurb and normal price range, our expectation was that they would be a step up from RCCL, pretty much across the board, but a step down from Cunard.
Despite a number of minor suggested improvements and gripes below, I enjoyed our cruise overall -- our itinerary was interesting, and Celebrity Equinox is a very nice ship, but in practice she did not prove to be the across-the-board step up from her sister company RCCL, that the marketing hype and pricing strategy would have you believe.
