I don't plan on spending any more nights away from home this year, so my list of places where I've spent midnight away from home in 2010 is as follows (non-consecutive stays in the same place marked with an asterisk, several overnight flights not tallied):

Nicosia, Cyprus
Juba, Southern Sudan*
Nairobi, Kenya*
Viana do Castelo, Portugal
Geneva, Switzerland
Belfast, Northern Ireland*
Addis Ababa, Ethiopia
Waterford, Ireland
Dublin, Ireland
Klingenthal, Alsace
Manchester, England
Priština, Kosovo
London, England
Kampala, Uganda
Cluny, France
Kidderminster, England*
Loughbrickland, Northern Ireland
Berlin, Germany*
Cambridge, England
Chişinău, Moldova*
Hucknall, Nottingham, England
New York, NY, USA*
Washington, DC, USA
Belmont, MA, USA
Dubrovnik, Croatia

So that's 25, up from 14 last year and 17 in 2008. (I don't seem to have tallied in the same way in previous years.) No wonder I'm looking forward to a December largely spent at home.
