Just a quick note about the flu. (We just returned from WDW
last week). I had been concerned about this too at this time of year, one reason we canceled our cruise part. Our family had all had a round of it two weeks before we went, but it was a quick one.
We live in the Northwest, so the strains on the East coast can be different. None of us (immendiate) family returned with anything.
I made sure that we always washed hands alot, and I used hand sanitizer lotion after as many rides as I could remember, and waiting in lines with railings, etc, that my daughter would put her mouth on. (kids.....)
My father did get the flu though, and actually had gotten it before we met up with them (they traveled in motorhome), but it got VERY bad while we were there, and he spent most of his days in the hotel room they rented. (I think he just wanted a private escape

.) My youngest niece got it too just as they were about to head home, and kind of spoiled their last few days of fun, and it was very bad with high fevers, cough etc. It took her over a week to get better.
No one coughed on us that I remember, but you TOUCH EVERYTHING without even thinking about it. (I was always sure we dressed appropriately though, and got dry after water rides, etc, and my sister-in-law did not do that with her daughter, (as it was warm, and it can be deceiving), so that is a possible reason my niece got sick, or more suseptible?
