When in Dubrovnik, you can expect to spend around €70-€230 a day during a trip to Dubrovnik, Croatia. The low end takes into account those staying in a hostel, pretty much eating street food and doing the bare minimum of paid-for activities and entertainment.
The higher end is for those staying in higher-end hotels, doing about an activity a day, and eating out around once a day at a typical restaurant in the center of the city.
