I studied in London and it was probably one of the best experiences of my life... seriously an awesome city in general and so cheap and easy to travel around Europe from (although the city is ridiculously expensive, as is most of Europe right now, so make sure you have the bucks if you are planning on being in Europe, but i took out a loan to do it and never regretted it).. obviously the cultural shock wasn't as big, but being in a program you meet so many like minded people you will be so busy having fun that you won't worry about the distance... that being said I'm currently working in south america and the experience of working is so much different (and much much harder to do with visas and finding work, etc), that I would definitely suggest taking advantage of the opportunity during school, because most likely you will not have another chance to live abroad again, unless you are really willing to work hard at it.
