thanks for all the replies.
white waltham - i have read so many good things about it. problem is that it takes an hour just to reach m4 from waterloo, it may be too much travelling.
i am trying all the locations on google map and it seems that it is quicker to reach rochester compared to fairoaks & redhill, although rochester is like twice the distance. Is this true practically or not, I am not sure..
let me see how others fair on the map...
