We spent six nights in Dundonald last week. It was a well run site. A bit off putting when you arrive to the big gates, but when we got over this, and were there for a while, we realised it was a very safe site. You pay at the Ice ring. It is 24pounds per night, including electric and showers. It was spotlessly clean and you are given a code for the gate and this also allows you access to the showers, kitchen etc. A very enjoyable stay there.
