The company that sold it to us have still not refunded the phantom booking fee they agreed to refund, and re-reading their original description of the event it was a far cry from a "private suit" at Silverstone. My overall opinion is we did not get good value for money. That is to say we paid far too much for what we got, not that what we got was not a fun day for all.
It is actually the first time I have done Silverstone. We had some fairly good grandstand tickets. National Pit Straight, not the start/finish line, sadly, but a good place to see some over taking.
