I totally agree with the previous poster and would like to add the suggestion of taking Airborne for several days before you go. I work in a school and also have two school aged kids and we went to WDW right before Christmas. I was so afraid of getting sick. We started taking Airborne about 6 days before we left, morning and night, and then contined to take it once a day on our trip. We also take multivitamins and we took echinacea (SP?) before we left for a few weeks as well. With all of the germs we were exposed to we stayed healthy and I attribute it to our boosted immune systems and answered prayer for good health (I mean that seriously). Good luck and have a great trip!
