Did the Sachsenring in 2007. I had a grandstand seat on the start/finish which wasn't brilliant. The bottom of the 'Omega' looked good, plus there was an enclosure on turn 13 (I think that it was the second to last turn) that looked good. It's a circuit where you may have to try hard to find a good view....it's small and tight, with plenty of grandstands but not great for 'sat on a grass bank' stuff.
The ride there is easy and the circuit is easy to find. The traffic is a bit of a pig....just like any other GP, get there early etc.
If you like a party, then try and stay at the circuit on Saturday night. It's one real mega blast...better than at the Spanish tracks (IMHO) More beer/bands/burgers than you can shake a stick at.
Camping is available on the hill opposite the main entrance. I didn't book, just turned up. No dramas.
I got my tickets on line, from the Sachsenring web site. You print them off yourself and everything worked perfectly....All very German.
Believe it or not, in 2007 it was the hottest GP of the year.....I baked, and loved it.
Thoroughly recommended...Enjoy.....
