The tour is over, and the money has not been spent. What should I do?

Hello, after the tour, if I haven't spent all my local currency, I personally often do the following:

If there is not much left, collect it as a souvenir, and then put it with your own photos when writing travel notes or sorting out photos. As a memory and proof, you will be quite proud to take it out in a few years;

If you have a lot of money left, and you are traveling with a group, you can consider changing it with the tour leader or tour guide. After all, they often take this route, and they still need it occasionally. Although the exchange rate is not necessarily good, it is better than not having to use it after you return home.

Find the corresponding institution or bank and exchange it for soft sister money.

Well, I have basically done all the above, and I hope it will help your trip.
