For planning your trip to and from the island of Hvar ferry (~2 h from/to Split) and catamaran (~1 h from/to Split) lines operated by Jadrolinija or Kapetan Luka are available. The most convenient connection with Split is the catamaran to Hvar. The catamaran is for passengers only (no cars) and brings you directly to the city of Hvar from where you can nicely walk to the conference hotel. Take a look at map of the walk.
If you are coming by car you can either take the ferry from Split to Stari Grad (~2 h) or from Drvenik to Sućuraj (~30 min).
