My 16yo is arriving at Kings Cross at 10pm next Saturday night after a trip to visit a friend. I want to pick him up by car (because I don't want him navigating across London late at night - he is not experienced enough). The station website says there is a pickup point in Pancras Rd. Drivers need to stay with the vehicle. There is no information about hefty charges, or maximum waiting times so I'm assuming that I can sit there and wait for him, even if the train is delayed. I am assuming there will be a space for me, and hoping it will be well lit (so I feel safe, as well as my son), and that my son will easily be able to find me by following signs within the station. Can anyone reassure me?
