There is no way to answer this , costs depend on so many factors and they cna change day to day so it depends on things like what city you are flying out of and to , what dates you are flying , what airline you use , how many bags you are taking , what hotel you are staying at , how much you'll spend on food , what you'll buy for souvenirs or extra things you might want like going to a club or buying some clothing and those are just the major items the best option os call a travel agency and ask about pricing for the date you want to leave for a return flight , ask about package deals that might include a hotel then take an extra 100 dollars or so per day for just restaraunt meals and the basics and add in what you think you'd spend on fun activities , taxis or a bus pass and so on.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
