What country will the U.S. dollar go the farthest?

I'm curious, which country would you say the U.S. dollar has the most purchasing power in? Is there a particular nation where the greenback stretches further than others, taking into account factors like exchange rates, cost of living, and the availability of goods and services? It's a question that many travelers and investors alike ponder, as the answer could significantly impact their financial decisions and overall experience in different parts of the world.
