There are a lot of websites that handles that kind of bundle. You can try priceline, hotwire or expedia.com. I would recommend expedia.
Sometime they give you more deals than what you asked. OR you can also try comparing car rentals. Sometimes it's better be a separate booking at least you can save more.
I use priceline and vroomvroomvroom.com a lot.
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.
