It has been posted to avoid concorde at all costs, and it's not far fromt he truth.
However you can travel independently and pick up bargains on the way. Fly with BA or Easyjet and once you land you can pick up accomodation along the way, it's cheap, fun and right now there's a lot on offer, plus the locals (I can vouch for Croatia) will be delighted to see "Western" tourists!
