Farnham's a really small hospital, my Grandparents and my great-grandfather used to be patients. Unfortunately my Granddad is type 2 so was probably treated by his GP, all in all they don't think much of Farnham's hospital.
I used to work at Frimley Park, and although my Granddad hated it, my Mum's experience in there recently was quite good (i'm not sure i'd recommend working there, not in the Pharmacy anyway.) I don't know much about diabetes care since i left before i got diabetes myself. My mum was in the Royal Surrey (got transfered from Frimley..not sure why) and she found it a bit impersonal after Frimley, but she wasn't in for diabetes. That's probably no help at all...
Farnham and Guildford (and the villages in between) are all quite nice but pricey, Guildford's deffinately the best place for shopping (don't get my Grandma started on Farnham's deteriation as a shopping town...). My parents (and the grandparents) live over on the Hampshire side of the border, in Farnborough and Fleet, these are popular commuter towns and house prices reflect this. I can see why Lizzie found Farnham snobbish (not that my Gran's a snob), Farnborough and Fleet are less so, but in my oppinion, are less pleasent places to live. Try Ash, that's at the end of the Hog's Back (major trunk road) from Guildford.
There are also large(ish) hospitals in Kingston and Redhill (i think...) and Reading.
