Location for London touring excellent. Coming from Wales it is easy to get to this site, (just ignore Sat Nav in the last couple of miles where it tries to turn you onto Tilehouse lane too soon, and carry on to Denham Green Lane from where you turn right onto Tilehurst lane nearer tot he site, as advised). Train from Denham Station to London, seems fast and efficient / on time. Trains mostly half hourly until later times when becomes hourly. About 35 minutes or so to get into Marylebone. So ideal for touring London. (Albeit late at night the trains are hourly from Marylebone!). The only faff element is this prepaying for the electric nonsense. The electric prepay app could not handle a change of debit card to make a second payment. We had to get help to log in to set up the account initially, staff v. helpful but a faff for everyone including them. However the card I used for the first prepayment of electric was subsequently cancelled by bank due to me inadvertently linking to a dodgy train booking site (I had to decline the dodgy payment, so card cancelled by bank). This meant for 2nd prepayment, I had to change card on the App. The App was not friendly in this respect as it does not seem set up to 'easily' allow a change of card. It defaults you back to the card you set it up with. Tried several times with about five different cards as it would not let me key in the full card details and then with half the info only allowed, it declined each card. I could not work out whether the issue was loss of signal or a problem with the App not accepting a new card. By the time got back to site, after 8 pm, all the Staff could suggest was 'switching to gas'. Fortunately we did eventually manage to get another card accepted and to make the second prepayment. So the prepayment app is not intuitive, not relaxing and not user friendly if you need to alter your payment card between payments. Also cost seems high - about £8-£10 a day even with being cautious about electric usage. £45 for 5 nights. I would rather just pay a pitch fee and not have all this faff about the electric being paid separately. Next time I will bring my own generator as a back-up as being about to be cut off was very unsettling. Be ready to go back to no EHU and gas only on this site!
