Hi,
Went to Seaview last year, it is a love thy neighbor site in my opinion. Some of the pitches had good views out to sea and others overlooked the nearby housing estate.
Although we had booked a awning pitch it was no where near big enough to accommodate a full size awing and in fact while we were there the wardens were measuring out the distance between vans as they did not meet the regulations and said they were going to reduce the number of pitches.
We found the area a bit run down and did all our shopping in Berwick-upon-Tweed. Not busting a gut to return to Seaview.
Regards
Nidge
