¡Hola! togtog:
If you like wishy washy answers that straddle both sides of an issue and refuse to make a commitment to either side, you have asked the right question.
What I recommend you to do is to conduct your own internet search using the search term "fuera afuera difference" (don't forget to put it in quotation marks). You will get tons of references and you will still not understand what the correct answer is. The respondents offer information out of both sides of their mouth at the same time and do not generally make a commitment one way or the other.
I suggest to you that whether you use fuera or afuera, you will be understood.
However, I did come away from my search feeling that "las afueras" is a reference to outskirts. See here ----> afueras. Geographically, is Cornwall on the outskirts of London??

Cambridge es un lugar muy bonita a visitar al fin de la semana en el verano. Hay muchas tabernas y hotels medievales a reserva por una noche o dos . Adicionalmente, Cambridge es muy famosa porque es la mayor ciudad de universidad en Inglaterra. Hay buenas tiendas para ir de compras y restaurantes excelentes para comer. Y por supuesto ir a pasear en batea por el río Cam.
Cambridge is a really lovely place to visit for a weekend in the summer. There are many medieval pubs and inns to stay in for a night or two. Additionally, Cambridge is very famous for being the oldest university town in England. There are great shops to go shopping and excellent restaurants to eat in. And of course, you can go punting on the river Cam.
