We've been to Orlando in Jan, never Nov, but while I would say it probably still won't be warm enough for pool/beach (60's, maybe low 70's if you are lucky), I would still do Jan. If you want to break up the winter blahs, that is more like half-way through winter rather than right at the start of it. A couple of years ago we went in Feb and lucked out with temps in the mid 80's - better for the pool!
