The Cambridge tip-off was your own post: "London I suppose is good for a lot of people (train connections etc) or Cambridge - because it's a very nice place with lots of interesting pubs and other places for non-alcoholic events. Oh and I mentioned a little while it has a fudge shop with free fudge. Cambridge is also easy-ish to get to by train the M11 or the A1."
