Cresciano is about 1.5hrs down the road from Averstal, 80 kilometres if memory serves.
Sorry, I meant RyanAir. You do have to go from the worlds shittiest airport (stansted) though - cue 45 mins waiting for bags on the way back/3hrs to sheffield.
Bergamo is Milan, airport code BGY, check with your car hire dudes about crossing borders, Hertz let you but some others might want extra moola, and if you cross into swiss by Bellinzona be prepared to have to buy this wierd sticker thing that allows you on the toll road, but costs about 50 euros.
If you are driving then the Clifford said 18hours from leeds.
Will see if I can find a number for danny and christina.
