Where to pitch at Garlieston?

Good morning. 

We are hoping to spend about ten days here in July/August.

Having read the reviews we are a little confused as to where to pitch?

One reviewer said the walled garden was the best for a van with an awning/sun canopy; another had experienced, noise and lack of privacy in this area. 

We are two people, no children or pets advice would be appreciated. 

Cheers murdy and mrs.
