One of our favourite sites, 

Not sure what size motorhome you drive, we drive a large Hymer and have never had to block the road enough for people to have to drive on the grass?

Also hard to get a site in such a great location without some road noise we have stayed here at all different times of the year and even being next to the road which can be noisy it has never ruined our stay.

Is good we don't all like the same things though it may make us getting a pitch easier if you decide not to visit again

Let’s hope the reviewer was using the dedicated motorhome service point rather than blocking the road at an ordinary point. I've witnessed that several times.
