Hvar is quite expensive, it is more expensive than the other islands in Croatia and more expensive than most of the towns on the coast. Only Dubrovnik is more expensive than Hvar. And on the island itself, Hvar town is more expensive than other towns and villages. Mostly the accommodation and restaurants and bars, especially nightclubs and beach/cocktail bars are the places where you will spend most of your vacation money. The prices are high but the service is great and the experience the best. However, if you want to save some money you can stay in a hostel or in a camp and prepare your own food from groceries you can get from supermarkets which are not that expensive as dining out.
