Just to Mostar. My whole trip is Italy (2 weeks for work, I'd rather not say where because it's a tiny little village), then Croatia (Dubrovnik, Zagreb, Plitvice), while in Dubrovnik we'll visit Bosnia (Mostar), Montenegro (Kotor), then up to Slovenia (Lake Bled, Ljubljana) over to Macedonia (Skopje, Ohrid) then a ten hour lay over in Serbia (Belgrade) on the way home.
