@chapor Last year we all had General Admission tickets. The cost to us was approx. £80-90 so in Euro’s that translates to around €110,00 I guess. I’ve just checked the official F1 site but there is no information available yet on tickets for the Italian GP.
General Admission has its benefits, if you’re willing to put the effort in. The two races I’ve attended (Monza 2011, Silverstone 2010) were great value for money because we took advantage of the roaming capabilities. By that I mean that we could go in any of the designated general admission areas (which were generous, especially at Monza). On the Friday you can access pretty much anywhere, including the seats opposite the pit wall, so you can have a seat wherever you like and spy into the pit lane and garages! For FP1 we planted ourselves in front of the main straight, opposite the pit lane, for FP2 we went to Prima Variante which offered a great vantage point.
During Saturday morning we explored the general admission areas (roaming ticket for anywhere you can only use on the Friday) and this really allows you to make sure you find a good place for the race. I would recommend the exit of Parabolica, on the inside.
Basically, the ticket is incredibly value for money, but only if you’re willing to walk around and really explore, which I’m sure you will!
Oh, and there is a pit-lane walk available on the Thursday afternoon usually ;)
