I really hope you are lucky enough to catch some good weather, everything will be twice as much fun.
I honestly dont think there will be lots of sun in the period you are visiting The Netherlands, November is always a gray/rainy month.

You should really visit Amsterdam, its a great city with lots of tourist attractions (BOATS!) but its also a great city to go shopping, visit a coffee shop, the red light district, etc.
Maybe you should visit Kinderdijk as well, which is 15km from Rotterdam: http://en.wikipedia.org/wiki/Kinderdijk

Enjoy your stay, and have fun. I wont be anywhere near Utrecht anytime soon though
