Around here everyone still seems to get monday off for Veteren's Day every year but I don't know about other places. I remember putting up a stink (to my friends and family) when I was little because I wanted my actual birthday off from school and not the monday before.
So, if some places are actually getting off November 11 instead of the monday before, then I don't know what crowds will be like. Still seems likeit might be less than summer but you can never tell.
I think those dates are probably worse. I've heard that Halloween time is getting to be pretty popular and there are big crowds.
