The quickest routes from London (west) are M25/A21/A268/A28 or from London (east) M25/M20/A28.
Note from Pete...
From Maidstone/Asford (N.E.) you travel along the High Street (A28) & turn
left at the William Caxton pub onto Small Hythe Road & it's 1/2 mile on the
right hand side.
Strongly suggest allow plenty of time - last year (2001) Tim picked up Marcel at
12noon, went through town/ S.London & arrived at around 3pm.
I'm going to head east myself, pick up Guy at 12.15 & get onto Blackwall
Tunnel approach - then the A2M, M25, M20 Ashford A28 turn off via Ashford
(the A2M after the M25 is plagued with roadworks).
