I have been down to Donna Nook a few times, at yes, its a fantastic place to go - you really cant fail to get good photographs. Im a little unsure of the timing, I have never been as early as the 10th Nov, although I have read that anytime in November and December is good. My own feeling is that early / mid December is best.
I was once lucky enough to get down there when there was snow on the beach - the light was amazing
I have seen lots of people only stay up near the car park / sand dunes, but if you are prepared for a (very!) long trek out to the sea, then you can also get good shots of the seals with the waves breaking round them.
Would be interested to hear back what you see on the 10th.
Good luck !
