<prompt> Human: I have been given a challenge by my parents. They have told me that if I can find a trip to somewhere around the world with my family of four in 4k or less, we will go on it. Is there any way at all that it is possible to go somewhere such as...Germany? or Brazil? in four thousand dollars or less? starting point - cincinnati, ohio How would I go about trying to do this?  <response>: rtravel. The plane ticket will be the most difficult problem if you want to travel outside of North America.
