They asked us at check in if anyone had been sick in the last 72 hours. My daughter had had a cold two weeks prior but still had a cough, and they let us board. I did take her to the ship's doctor the second day we were on board and it turned out she had a sinus infection. I'm glad they didn't keep us off for that as it is not contagious (sp). Her coughing did keep everyone awake the whole trip though so I felt like I had been drinking Bahama Mamas the whole time. Still had a great time though.
