I totally agree OP. I also think the whole of the south west in over rated, and it takes AGES to get to from most of the UK! I mean hours and hours and hours!!!!!!!
A friend of mine went to Penzance in Cornwall, to a wedding in May, (she lives in Northampton.) It took SEVEN AND A HALF HOURS to get there and TEN to get back, because there were a couple of traffic accidents on the way back.. (It's about 325 miles from her.) She said it was not what she was expected and was flat and dull and she preferred the Cotswolds and Wales!
I am also not a fan of the south of England, and south east either. I do think the home counties are pretty OK, but again, not as nice as counties further North. I'd rather have Wales, the Lake District, The Peak District, Shropshire, Staffordshire, and Yorkshire. And Scotland (obvs!) And also the Cotswolds are pretty. Snowdonia is beautiful, and we go there at LEAST once a year.
Also, as I said earlier, Cornwall (and Devon) are both a MARE to get to, and just seem so far away from everywhere. And as has been said, over-rated.
YANBU OP! It's very odd that it's so revered. I wouldn't live there if you paid me.
