i still have not traveled the world by means of transportation... but for me the best countries to visit are those in europe.. i like greece and italy. for me these countries resemble the ancient civilization.. France and UK are also viable countries to visit... they show the modern world and there are many chic places for you to go to... BON VOYAGE!!!
every country has something different to offer and we won't know about it unless we visit it ourselves. I'd like to go to Czech Rep. because it's not that famous like Scotland or Ireland but it's got pretty much the same to offer. You just have to know how to explore it
