Changes

 One option is to walk out of the terminal building, through the car park, and follow the road signs pointing cars towards the M20. Unfortunately there isn't really a safe place to pull over until the first bus stop, about 500m away. By this stage traffic is often going quite quickly, and some of it is now local traffic, but it is mostly port traffic, and you should be able to convince someone to stop. A sign would be useful (such as 'M20').* I waited over an hour here, and walked If you walk further to you will find a better spot, but only found the next bus stop, another 500m 500 m or so further down the road. Conditions were no better, but I got a ride in about 5 minutes -Nomad Kat
