For the first time we did not book a return to the UK, going on the basis of playing it by ear. I did some research in Paris, saw about £45 for a single from Calais. So pull up in Calais ( with just 30 mins free parking outside ticket office ) and in I go. DFS "how much for....." €156. "PARDON, it was was £44 on the internet". "Oh yes, that is advance booking, if you go tomorrow it will be €56" "I'll try next door". Next door is P&O. "H O W M U C H, €165, you are bigger robbers than DFS". The woman was not over impressed with this. So I paid DFS €56. The girl was far prettier too, blue eyes that could charm the snipers from the trees. Then I went to park in the free carpark to stop overnight and found the port offers 30 mins free WiFi. On the DFS web site I was offered immediate transport for £44, but the deal was done then. I sobbed pitifully for some time. The motto - plan ahead - in Calais port you can probably buy a ticket much cheaper using their free WiFi than talking to a person. But it was not all bad, we had good food and wine on board so had an extra few hours in France and got on the 04:00 ferry.
