brighton le sands has several big car parks along the water from the airport all the way to dolls point, my guess is six or seven. it all starts at the end of the eastern distributer/southern cross drive. so there would be some good highway/freeway roads almost to the meeting point.
Crawling with cops though, including unmarked cars, so avoid it at night. If you head a little further down near Ramsgate, it's much quieter the further you go.
(This was my feeble attempt at sounding like I know the place lol)
Paul have you been giving out those stickers???
