If money is an issue, stay out of countries on the euro. They are far more expensive than most anywhere else, and most of the world is not on the euro. The next part is purely personal. Is there a pressing reason to visit a place? My first trip alone was to Korea because my son was teaching there. I also traveled in Japan for a week because the plane stopped there. Often you can stay in a city where the plane stops as long as you eventually continue on to your final destination. Surprisingly, both countries are easy to travel in. Public transportation is excellent, all signage is in English, and both countries are very safe.
