I tried jackie again Nige and mentioned yourself and SES and still had no luck!
I tried all the hotels on
http://nurburgring.org.uk/ and only found one with
a vacancy and it was it's sister hotel which didnt have any parking plus not great reviews!
I managed to find a place called the RING-RACE-FLATS in adenau pretty close to the town centre and have booked there. (no bad reviews that I can find!)
I got a fairly good deal on it! luxury flat 90 euros a night, ok so no breakfast included but how many local brass do think I will get in that jacuzzi
