We are on this tour August 2. These countries use four different currencies - I know of people who have used ATM's and their card was compromised - when they arrived home they discovered that they had additional charges. I am considering taking a small amount of currency for each country for incidental purchases such as a bottle of water or a glass of wine etc. However - I am curious to know what currency you have used to tip the Guide and the Bus Driver?
I would appreciate your input.
