IMHO, when most of the kids are in school, it's cooler and your body isn't so stressed, and things have less heat to "incubate" in, lol. I always go the end of the year and have never gotten sick.
Also, healthy is a matter of perspective. I'm asthmatic and I'm going in August - not necessarily the "healthiest" time of year for me... However, someone else may have other issues in the cooler weather. Bottom line to help avoid getting sick is not to get run down and to wash your hands constantly.
