I am planning on visiting both Southeast Asia (Vietnam, Cambodia, Laos and Thailand) and Eastern Europe (Prague, Budapest, Kraków, Berlin Amsterdam). I am up in the air about dates.
My first thought is Southeast Asia sometimes between January and March about 50 days then Europe may and June.
The other option is to start in March in Asia then head to Europe then home
Other than the obvious benefit of saving on airfare when would you go.
