I returned from this trip last Friday, I had a great week and I am planning to post a review soon which I hope will be useful to you. Just briefly, the Croatian currency is the Kuna of which you get almost 10 to the pound so it is quite easy to calculate back to sterling. If you divide Croatian prices by 10 you won't be far off eg 60 kunas would be about £6. As to how much to take; I didn't want to be left with lots of Kuna, (it's different if you come back with Euro's which you can use on another trip) so I took £150 worth of Kuna. This was enough to pay for lunches, bar drinks, wine, water & tips. My excursions were already paid for when I booked but if you pay for them there it is in Kuna. I did go on a boat trip, cable car and city walls in Dubrovnik which were extra. I didn't spend very much on gifts (the airport takes Euros as well as Kuna). I also had a massage in the hotel salon, again paid for in Kuna, as they didn't take cards. It seems a lot of places don't take cards however in the second hotel there is a cash point machine in the hotel foyer. I ended up drawing another £20 from the cashpoint, (with a card that doesn't charge you any extra) it was probably the massage that blew the budget, but I hope that gives you an idea of how your money goes. As to dressing up, people tend to change for the evening, but its quite casual so you can dress as you feel comfortable.
