We were originally travelling from Waterloo, but when we checked out the prices and times of trains from the East Midlands, plus factored in an overnight stop that would be needed it was going to be very expensive. There was no way we were going to drive to and park at Waterloo, so we decided to go from Ashford. We are staying in the Travelodge the night before, £26 room for all of us, and parking at the station. Yes it's £11.50 for 24 hours, so will be £57.50 but that was still less than one return train fare to Waterloo from where we live!!
