We stayed here at the end of July 2024 to make a trip for an event to Wembley Stadium. This is a perfect site to get both to Wembley and into central London. It's an easy 30 min off road walk to the station and then the trains are very frequent and take 10 mins and 20 mins respectively. They run late into the night too - just take a torch for the last half mile back, although there is a lot of parking at the station too. As for the site, it is great. It's next to a nature reserve so you really feel like you are in the country. Yes the small planes and helicopters at the air field next door during the day could be intrusive for some, but at night this was one of the quietest sites we've stayed at. There's loads of wildlife so we could hear owls and our first every bullfrog, and see bats swooping around. It was magical. The electricity trial worked no problem at all and the reception team have a really helpful QR code plus alternative means of accessing the website should you have any problem with your own device. The cost is incredibly reasonably - ok it was a warm weekend in July but we spent a grand total of 55 pence for the night on power and our refund came through no problem at all. The site is also incredibly easy to reach from the M40 and M25 and you are not aware at all of how close those major routes are. We've tried the other London sites and for convenience and access this is our favourite.
