hi there,
I too will be communting shortly at lgw for ba. I will be travelling from up north so to would be looking for b and bs. My friend who lives at lgw said she will email me with some numbers, so once i have received them i will pm you. Also worth looking in back of BA news as I remember last year staying at a place near airport and with bed and breakfast and transport to and from airport it was only about £17-18 pppn.
