Last May 03. one of my little ones got the Norwalk virus, he was horribly sick high fever, hospitol x's 2. The others got it the night we returned home as soon as we put the luggage down they fell apart.
I was neurotic about going again, lets face it you are picking it up from the kids touching hand rails things of that nature. We went back in December and we did exactly what my pedi told me to do.
It may sound a little nutty to people but we went noone got sick, so therefore I am going to do it again..As you said using that hand gel constantly is a really big thing. Bring your own stroller if you have little ones! And he also told me to bring a can of lysol disinfectant spray and spray the entire room. Paying special attention to things like light switches handles, remote controls. And most important..... people don't realize it takes 20 minutes to start to work. So spray it like crazy,( kids out of the way of course) and go for a walk.
By the way my DB thought I was being a nutcase. and had alot to say. BUT took the can anyway and did his own room Just in case!
Last October a girlfriend of mine went to disney with her extended family, and was doing the hand gel thing and I guess driving her family crazy. So the wiped thier hands all over the railings at Little mermaid and all wiped them all over her, To show her how foolish she was. Well you guessed it 2 days later she got violently ill.. It was not pretty if you get my drift. Her DH is still in the doghouse about this.
It wasn't so funny in the end. (literally
