Thinking of a family trip to Croatia with a relatively good deal for the summer from ORD. We were thinking of flying into SPU and drive to DBV. It looks like there's a bit of Bosnia in the way. How is the drive? Are there long stops at the border? Can I take a rental car from Croatia through Bosnia? Our trip would be in mid to late August - I assume the crowds will be crazy, but if anyone has suggestions for quieter areas in the region that would be interesting, it would be nice also.
