How to pay for expenses?

It is better to pay in advance for everything possible, for example, air tickets, hotel rooms, etc. You can even save money. And already during the trip you will have to pay with a bank card or cash. If you go beyond the country, you will receive a medium -level international bank card in advance so that it is not blocked for transactions abroad. In addition, you will need money for certain expenses. That's why you decide how much money you can take in cash, and how much money is on the card.
