Do it - it's brilliant. Have a look for the Touristenfahrten days on the Nordschleife
here and then start arranging it.
The cheapest ferry crossings I found were with Norfolk Line from Dover to Dunkerque and I stayed at a local guest house, which was a great experience! There are plenty of hotels in Nurburg, but they fill up quickly when there is an event on the GP circuit so choose your date wisely and book early.
Have a look at
Ben Lovejoy's Nurburgring Nordschleife website for advice and places to stay.
I'm hoping to go back again next year, it's a fantastic place and well worth spending a few days there.
