I visited Brooklands a couple of years ago with a party of others. The all-day visit included both the 'Concorde experience' and a visit to the simulator. The volunteers have done an amazing job restoring the simulator; there were too many of us for everyone to have a turn at the controls, but even watching from the back of the flight deck was an experience - especially when we flew under Tower Bridge on the way to London Airport!
Hope you've booked a ticket though?
Lots of other attractions at Brooklands - as well as Mercedes-Benz World
