Did my PPL QXC landing at Lydd a couple of years ago. Everything and everyone was fine.
On another occasion, on a choppy day, I had to land there after a passenger had puked. I call up on the radio, explaining the situation (I didn't have PPR), and they did everyhting could to help, even providing me with a bucket, sponge and disinfectant to clean out the plane.
As for the tower, they have always been friendly.
Watch out for the non-standard join into the circuit though and , yes, keep well away from Dungeness power station.
