If a CL will do rather than a site, then strongly recommend CC CL at Little Hougham Court Farm, listed under Dover (George & Wendy Stokes). This farm is two minutes from the A20 jnc just outside Dover (the Courtwood/Capel le Ferne/West Hougham exit). You can be at the ferry port in under 10 minutes, with a completely clear run and no bottlenecks to worry about. The CL is well used to late/early arrival/departures for the ferries, so you can get in and out easily without disturbing anyone. Very helpful owners, nice spot (no hook-up), and very handy. Worth a try maybe? Richard.
