£50 for ferry Dover to Calais (Based on Sept, one car, one passenger, 3 days)
Directions from Calais to Nurburgring
~£10 per lap (cheaper if booking multiples) Not bad for a 20km+ course! Pay that for about a mile Go-Kart track!
~£20 a night hotel - although there are camp sites and guesthouses around the area
You can get organised trips but far more expensive and not half as much fun!! :laugh:
Would certainly be a good few days away 
(Apparently, you need more than one day to get used to the circuit)
Very useful website from Ben Lovejoy who spends a lot of time going over there. He's already had about 40 trips over.
