I went in may this year, absolutely awesome loved every minute of it, i only did 5 laps but spent alot of time walking round perving on all the motors and also driving on the surrounding roads.
There are photographers all around the track taking snap shots of you so you just need to find the right websites to find your pics.
We went from sheffield to dover got ferry to calais and stayed over at a cheap hotel then went straight to nurburg, had 2 nights at nurburg then drove back to brussels for 1 night to break the journey up then back to calais from there and back upto sheffield.
Ferry was £50 return with sea france
European breakdown cover was £52 with AA
F1 hotel was £29 in calais
2 nights in nurburg was £60 B&B
1 night in brussels was £35
Fuel was £260 for the lot 1330 miles including 5 laps of the ring
Ring tickets are roughly £20 a lap or £70 for a 4 lap ticket
Then basically whatever you spend on food and beer!
As others have said just be careful and enjoy it
