Swerv, you are leaving at 07.30, meeting at 07.15

Katie, from there its a little bit of a drive in the morning but not tooooo far I guess. Slightly closer is the Travel lodge in Central Milton Keynes, that is pretty much opposite the A5. Even better is if you can find a B&B in Towcester, then Silverstone will be within sniffing distance in the morning.
