Hi Piglet,
This is our third trip, virgin in 2004, caught the bug so had to come back in 2005, unfortunately a wedding in Canada ruled out 2006 (but managed LMES at Donnington as compensation). Watched it on MotorsTV last year. Spent the whole 24 hours misearble 'cause I wasn't there, so had to come back this year. I also have the added bonus of a wife who's a motor sports nut.
Each time we've gone through MRI. To be fair your guaranteed a spot if you book eary enough and I can't complain about the service. Don't know what's going to happen for us re zoning on MB. All I know is that we're on there somewhere.
