I don't think I have ANWB maps, mine just have the LF routes on, which should be on the ANWB maps as well. I should have a look at stanfords what the ANWB set looks like, curious now.
As I said TT's thread, if you book your bike on the dutchflyer (stena line does tickets without the train as well, which can be slightly cheaper) you might get a quote without the price for the bike included, even if you tick the right box, and you'll have to pay extra afterwards.
