Depends. If you want warmer weather try southern europe such as Spain or Greece. If not, there are many places. Berlin, Amsterdam, Copenhagen, Prague etc. November is not bad despite what some say. I've traveled during the "off" season and it has its' advantages. Things are cheaper, no lines to see attractions and it's not overrun with the tourist hordes. You get to see the "real" Europe much more. Personally I don't mind cold weather in November,it's super after a long, hot texas summer but that's just me.

Was in Paris and then Barcelona at the end of November - beginning of December.

Paris was rainy and gray at times, but still beautiful. Barcelona, on the other hand, was like a weather paradise. Every day was sunny; temps were in high 60's (F). Flying into Barcelona from Paris and looking out the window to see the Mediterranean and palm trees - WOW.

Checking out Barcelona, Lisbon, Prague, Budapest and Athens...Trying to stick to just 2 cities since we are going back to Europe during summer of 2009 anyway. Thanks for all of the nifty suggestions....
