* What is the best way to go see the British GP?I can't say for sure what is the best way, each to their own really. I drive up on the Thursday (from London) and camp next to the circuit by Stowe, when I say camp, I mean sleep in the back of my van

The campsite has hot showers and toilets (although the toilets aren't hot obviously...). I think its £15 per night, and they have 24hr security. Good atmosphere, one group even had their own karaoke set up, complete with TV showing the words!! There are designated 'quiet' areas if a good nights sleep is essential..
* What are the General Admission areas like?If you don't mind getting there at 5am, and guarding 'your patch' for 6 hours then fine. Not for me though, £230 for a 3 day pass and a grandstand seat at Stowe, is good value in my opinion.
* If GA is toopacked I'd rather get a grandstand. Would anyone recommend good grandstand seating which won't break the bank?See above, at Stowe you can see the cars coming out of Becketts, down Hanger Straight, round Stowe, through Vale, round Club and then going up towards Abbey.
* Is there any same day train service from central London to Silverstone, including connecting buses? Is this OK or too much of a nightmare to contemplate?No idea to be honest.
* What is Silverstone camping like? A guy at the pub this evening said he was robbed by pikies at Silverstone in 2007, and many other campers were. Is crime an issue?See above. Check to see if the campsites offer security.
* Question for people who normally go to European GPs but have been to Silverstone: Is the British GP worth the hassle and expense?Compared to Spa I would say similar. The traffic getting to Spa is a nightmare, the British GP isn't great either. Facilities at Silverstone are better than those at Spa, by a country mile (proper toilets, better choice of food). If you live in London then go for it, why not?!
