We were there a month ago and my son vomited 6 days after we were there. Thank goodness no one else in our family got it. My children have also vomited while we were there on 2 other occassions (at least 5 days into the trip). So our record is 3 vomiting episodes out of 6 trips. Getting the vomits at disney is common IMO. I also know a family that got back in Oct. of this year and they all got the vomits, including the in-laws that went with them. Just wash your hands(especially before you eat) and don't touch your face and it will help decrease your chances. Everyone on here wants to say, they caught it in the plane, before they got down there etc. but I know alot of people who have gotten sick from disney. Wish disney would put some sanitizer posts near their rides, like they do in hospitals but I guess they wouldn't "look good".
