Unfortunately I failed my stage 2 FEAST today. I guess I'm just not made of The Right Stuff. Only 1 out of 7 of us got through to the DART.
I just thought I would give a bit of advice for people who are driving because I worried about this a little bit. There are visitor spaces in the NATS car park, probably about 16 overall and these remained half full up until 8am, but it may be that it wasn't a particularly busy day. You can also park on the road immediately outside the NATS compound (which I did). As a last resort you could park in the shopping centre car park, but I think there's a £2 charge for 6 hours and there's a bit of a walk (10-15mins) to NATS from there.
Also the day is rather straight forward, so don't worry too much about that aspect of things, everything is explained before you have to do anything.
Good luck to all.
