UK - South Coast (Dover area) all year round site

Im looking to have a bit of a shake out for around 5 days before we depart Bighty and head into Europe for the remainder of the year.  The site needs to be located around an area close by to the port, we are planning on heading to Calais or Brugge, 1 st stop is gonna be YPRES and Flanders.

Would appreciate any assistance with a reasonable site, we will be heading down to the coast on or around the 2 Feb 13.

many thanks Rob
