just wondered how you got to port from London?
Can I say, from my observations on Saturday:-
Those cruisers who braved our roads and booked car hire had a very good idea. National Car Hire has a drop off location within walking distance of the port. You can drive from London to Dover easy on M20, and then drop off luggage and check in and the driver just drives it back and can walk back to port, have ID.
Can also stop at Leeds Castle, Dover Castle, Canterbury on various routes.
Note LONDON END we have lots of rules congestion charge poor parking, or expensive, so not good for driving in and around London.
Train Dover Priory is good but requires taxi transfer, they were frequent back and forth, but queues could develop at peak times. Dover priory is reached from London, Charring Cross, London Bridge, Victoria, or St Pancrus.
I do not recommend National Express. Stops a bit far away.Long journey.
I saw a lot of people coming by taxi from the train, also lots walking to/from Port, and struggling with luggage, its a long winding road, over a bridge from the port, over the railway line with trucks every few minutes, going to the ferries, OK If you haven't your luggage Dover town is OK in 10>15 mins, but with luggage an issue.
