So these are your options and as you can see accommodation is not a problem.
But we must warn you that Inferno Gaming Festival is held in peak of the summer season so if you wait for too long there may be a chance that all accommodation will be reserved or sold out.
Also during the summer season the prices of accommodation are skyhigh so if you are interested to go to Inferno Gaming Festival and to vacate in beautiful city of Zadar reserve your accommodation as early as you can.
