Ok, just had a look...

I guess we will either be going
M4 - M40 to junction 11 - A43 - M1 junction 15 - A45 .....
OR
M3 - M25 - M1 junction 15 - A45 .....

Dunno yet but would guess second one is probably easier for us...
Not quite the same way as you I am afraid... I guess we could only meet once there really!!!
