How long is a piece of string question I know but would like a rough idea and then take bank cards as a back up. Going for 3 nights and there half a day on the fourth. Plan on wining and dinning by night and seeing the sights by day. Would be handy to know how much meals set you back, a beer, bottle/glass of wine etc so I won't be totally shocked when I get there and can then work out some sort of daily budget. I realise this will vary across the board but just after a rough idea and some tips.
