A word of warning about Dorset. It's bloody primitive!
A few years ago the Wife suggested renting a cottage somewhere for a week to have a holiday with us and the dogs, plenty of country side and beaches to stroll around, that sort of thing.
So that little imp in my brain pipes up 'I hear Dorset's nice', to which she agrees. She even lets me carry out my plan of slopping off down Bovy for two days. Anyway we arrive in the village (out ot the west end of Dorset, Bovy was quite some distance away). No where, and I mean nowhere accepted electronic payment, and there was no cash point. The yokels for several towns and villages in each direction only understood cash. Eventually we found a supermarket with a cash point a town over from us, but it came as a shock.
Equally, the only time I had decent phone reception was on a hall, at some ancient and very windswept iron age fort out in the middle of nowhere. The locals seemed to communicate with smoke signals.
I would say the area around Bovy doesn't seem to be plagued as such, and everywhere is fully up to date and able to use cards etc. Jsut saying if you push out further afield be prepared. Let's put it this way, I'm from the Fens and live out that way, and I think the place we ended up is primitive.
