MrsC and I are having a weekend in that London in a couple of weeks time. For reasons best known to my better half, we are staying in Dorking (to be fair, we need the car on the Sunday and I suspect anywhere closer in was prohibitively expensive by the time you consider parking).
We therefore need to get into London on the Saturday and will be using the train. Does it make sense to buy the tickets in advance, or do we just turn up and pay?
Thanks
