Ashford International Railway Station, though the name is a railway station but other than the trains, nothing makes it feel like one. There facilities are top class which can easily compete with some of the world's best airport. They have all kind of facilities like different lounges, big parking space(2000 to be exact) etc. It is known to be one the largest Stations in Europe. You will find the fastest connectivity between different stations. They have this highspeed JAVELIN service which was launched on 29th June 2009.
Ashford is good city too.....you can easily find places to visit to. Trains from Ashford International to the continent take just an hour, which is much faster and cheaper than a trip to the airport.
This would be a great option and i'd prefer train if it takes same time as a flight cause i can see the scenic beauty of the country side too.
