ooh nasty. My DD3 has had that, and me, and I felt rotten with it.
I had it as a teen, and my uncle terrified me at that time by teeling me about isolation........not needed now tho as easily treated with penecillin (if you aren't allerig that is).
one thing tho........about 4wks post infection, DD3's hands and feet peeled, and I lost skin from my hands too altho I cannot remember about my feet. look out for that.
am sure that holiday should be ok for you, but what about your family??? cannot remember how contagious it is, altho when DD3 had it, neither her sisters caught it. Mind you, they did get strep throat which IIRC is connected as it comes from the same bacteria.
