Just finishing 3 weeks away where I've visited:
Italy:
Milan - 1 cathedral, 1,000 pickpockets
Lake Como/Bellagio/Lugano - beautiful scenery if the weather holds
Pompeii/Naples - amazing history and the Maradona tributes are fantastic. Utterly chaotic - loved it
Romania:
Bucharest - a hidden gem. Beautiful with lots restaurants
Dracula's castle/Brasov - a long day trip that on balance probably wasn't worth it even though it had been on my list for a long time
Poland:
Krakow - without trying to sound controversial, and fully acknowledging the atrocities that took place, Auschwitz as a tour lacked the horrors of the killing fields in Cambodia. As a city it offers little unless you want to spend the day on the lash
Lithuania:
Kaunas/Vilnius - nice day trips but little to do. Kaunas has a cool university town vibe with some decent restaurants on the main strip
As always, I've enjoyed seeing new places.
