Prague or Lisbon in February?
 

Prague is sometimes very, very cold and windy in February. Lisbon may (or may not) be very pleasant and warm

I know someone who lives outside Lisbon. From what I can tell, there's not much of a winter there. Lots of green even in January. Not sure what weather you'd find in Prague, but I don't think Lisbon would disappoint. Great, funky city. <BR>
