Copy of my reply to a similar thread a while back:
I have been to Silverstone 4 times in the last 6 years. Bronze is now dead.
Bronze used to be epic, you could sit anywhere from Becketts all the way round to Bridge with great views. Club corner banking was great as you got a view from Stowe right through to the Abbey Chicane.
However, first they built a grandstand on half the bank at Club, then the built one on the straight to Abbey, and then this year that will be the start finish straight so I would assume the whole area will be Grandstand only. They have also got rid of the large Bronze area infront of the Maggots/Becketts grandstands.
So, you will definately need a Grandstand ticket. I had a Grandstand last year. You get an allocated seat for the Sunday, but a roaming ticket for Friday and Saturday so you can sit in any grandstand. Naturally, I sat everywhere.
On Sunday we were in Luffield B, which overlooks the complex and final corner. It was a good spot on the old layout, but with the new layout you would want to move round one to Woodcote A to get a view down the new straight from the Arena section. With the start finish straight moving, these tickets might be less in demand this year.
On the Friday and Saturday we moved around. the Arena grandstands are good for views of the Arena section, and you are quite close to the track. However, your view is limited to just the Arena section. The Beckectts grandstand opposite is higher up, so not only do you get a view of the epicly fast Maggots/Becketts complex, but you can also see over to the Arena and down the Wellington straight (might want a zoom lense though). The only issue with this grandstand is it isnt covered, so if it rains, you get wet, and if it doesnt, you will be sunburnt, guaranteed. (amendment, they have announced that Becketts will be totally covered this year!).
Stowe grandstands are ok, although not covered. Then you are round to the as yet non existant new start finish straight grandstands. The new pit building will block your view of the Vale, so you are limited to a view of the main straight only. For the same reason I was never interested in the old main straight grandstands, these will be a waste of time. Other than the start you will see no action.
So, my recommendations are either Woodcote A or Becketts. But make sure you move around on Friday and Saturday though.
Oh and also, with Bronze we were arriving at the track at 5:30am and fighting for a space. With a Grandstand you rock up when you feel like it and wander into your seat.
Kangaroo TVs are brilliant. Definately get one booked. As for food, you can take some yourself if you like. We used to do this, but carrying a bag round all fay gets very tiresome very quickly, so we now just take snacks and buy food in the circuit. Expect to pay stupid money though, but to me not having to carry a 10 tonne backpack was worth the £8 burger price!
