In most clubs and popular places, you will have to pay to use the toilet (sometimes up to 2.00 EUR ) What can I say, take a leak before you leave the house. Also, exchange you money in the exchange office, not on the street. Don't buy drugs from locals at clubs. When visiting Brioni, take the bus to Fazana and the ferry to Brioni. Don't take the boat from Prorec or further up as you will pay 3X as much and won't see anything special.
