There's a few land bridges in EB that aren't there in RTW. There's 2 between the Med and Black seas, and another at the western edge of the Crimea. Sicily to "the toe" is the other obvious example. There are also some canals that allow shipping throught that you don't get in Vanilla. The Corinth Canal in Greece and the Red Sea Canal in Egypt are 2 I can think of.
Oh, I forgot the land bridge at the mouth of the Gulf of Corinth, and across to Euboia in southern Greece. And maybe some more in Scandinavia, I'm not too sure about those.
