You get a better exchange rate when you use a bank or ATM to convert your American dollars into whatever cheap, colorful and ridiculous currency is being used in the country you are visiting.
Make sure you get all necessary vaccinations before traveling to another country. This means ALL vaccinations because other countries are cesspools of disease and infection… except those that have functioning cesspools, ironically…
