We feel so spoiled by Celebrity that it would be hard to change to another cruise line at this point. We are also looking at the Aus/NZ trip on the Mercury. Are the Mercury and Galaxy sister ships? And how do they compare with the Summit/Millennium ships that we have previously sailed on? Are their staterooms similar (Concierge Class)?
