Right - I'm fairly certain of the times now, so this is going to be the itinerary of the 2008 Briskoda nurburgring trip!
Leave Dover on a ferry at 8am - arrive Dunkerque at 11am EU time.

Travel gently to the Center Parcs at Heilbachsee near the Ring - approx 4 hours driving, maybe 5 with time for lunch - only 250 miles odd - Not much delimited autobahn either....
Arrive at C.P at about 5pm. Check into the cabin/s, and then nip to the Ring, for the hour and a half session in the evening - can buy tickets and do sighting laps.

Drinks at the bar in the evening + food.
Sunday and Monday will be full time Ring action.

But ultimately, people can do what they like really. No doubt, there will be drinks and food on each evening.
Ferry back from Dunkerque at 4pm on the 13th, arriving in UK at 5pm our time. This time could be flexed to avoid rush hour. Might be able to grab the ferry 2 hours prior.

On Norfolkline this trip is currently around £45.

It will be down to the individuals to book their own ferry through norfolkline.

LINKY:
Norfolkline ferry services to France (cross channel Dover Dunkerque) and Ireland (Liverpool Belfast/Dublin)
Cost? Well, it's looking like the cabins will be 759 euros for the whole period. So this is around £75 per person based on 8 people sharing said cabin for the duration (exchange rate fluctuations possible). This is CHEAP, but ultimately it's just a bed for the night - food and drinks can be had in the bar. Breakfasts and lunches can be grabbed at the Ring, and surrounding areas. Self catering anyway - a degree of fending for ones self
Fuel? Well, you're looking at 250 miles of driving from Dunkerque, so factor in 500 miles of EU driving, whatever you need to get to Dover + ring laps. I'm planning on doing 30 laps over the weekend. I reckon for me, that would be a tank of fuel + another half on track use alone. Food cost will be negligible - perhaps £10 for food, then there's drinks too.
Laps of the ring are approx £14 each. The more you buy the less each lap is. Buying 15 laps works out quite good value. We'll find out exact prices at some stage though. There is also the option of taking out insurance to cover you on the Ring. Personally I'm not going to be going hell for leather, risking my neck and my car - so I am not bothering with insurance on the Ring itself. Best check you have cover for driving in EU though.
Everything will be going through me though - I will need 100% commitment from those wanting to go. Please PM me the following details below, and I will PM back how you can pay me the £75 for the accommodation (paypal, bank TR, cheque). Once 8 people have paid me, I will book a cabin at center parcs. Once another 8 pay me, another cabin will be booked - and so forth.
DETAILS NEEDED
1) Full Name/s and address
2) Car type and reg (not 100% necessary, but you never know)
3) Contact telephone
Who's up for it? I won't bother PM'ing myself.
