My entire family came down with the flu years ago, and we were all miserable. My son came down with it first, and in the end, 6 days later we all had it. We were home, miserable, but home. I cannot imagine how much more horrible it would have been at WDW. To know it was all so close, but we were stuck in a hotel room, sick. I think it would change my families view of WDW forever. Please, postpone.
