We had a great week. The site was fantastic very peaceful and only 50 mins from Van to the city centre. Its location for exploring London is brilliant with the Abbey Wood train station only a 10 min walk away. We had a 7 day travel card for zones 1-4 that cost very little and worked. Make sure you set the correct start day when ordering these online from here http://visitorshop.tfl.gov.uk/tfl/london-travelcard/ The wardens work very hard to keep the site very clean and well attended. They also gave us excellent help and advice on arrival. If you are using the Dartford crossing on the M25 to travel there don't forget to pay in advance or within 24 hours of crossing, or you'll be penalised. You can't pay by cash at the crossing. https://www.gov.uk/pay-dartford-crossing-charge
