Hi list, What about Sorrento, there are good conference facilities, hotel rooms can cost as little as 60 euro per night, it's warm (temperature in between 10 and 20 C°), there a lot to see and to do(For example it's only twenty minutes from Pompei and fifteen from Capri) there is good transport, prices are low (It is south europe), I can get it organized if you don't want to go to siberia.
