We had some niggles/problems during the first few days of our cruise: butler was rather absent, especially when time to help us unpack, non-existent staff on deck 16 when sunbathing and wanting a drink, or even a mat for the wicker sun lounger, some false charges on the account etc etc; however we addressed them with the ship and plans were immediately put in place to ensure the rest of our honeymoon was amazing. They couldn't do enough for us. During the first few days of teething problems we saw a lot of unhappy guests, but nobody spoke up. This seems foolish as there's no point leaving the ship cheesed off and putting the cruise down if you don't say anything at the time. Mistakes and problems will always happen: it's what the company does with your complaint at the time that's appreciated and can make all the difference. Have booked our next cruise with Celebrity for 2017.
