I believe this ship is not clean. I was not sick when I boarded the ship, but by day 4 I was very sick. So were so many of us. Four years ago on this same ship I saw employees cleaning everywhere - hand rails, elevator buttons, elevator doors, and I saw purell dispensers everywhere too. Not this time. It did not seem as clean; the attention to detail in the service was different. 3 of our party saw the onboard doctor. i had brought antibiotics with me, but am still sick. two of our party are going to the doctor tomorrow. I went today. There is something wrong. Many people complained of being sick. People coughed and hacked constantly in the elevators and in the buffet dining room. Not good.
