At the end of the tour, it will be time to give your voluntary contribution to the guide.
🛑 If you have to leave the tour before its completion, you can always give your guide your tip before leaving.
🡪 In what currency should the guide be paid?
The ideal option is to always pay in local currencies. If you do not have local currencies, nothing happens, you can pay with important currencies such as the Euro and the Dollar.
💱 Also take into account what the guide tells you, since some local currencies can fluctuate a lot and that is why some guides prefer to receive dollars or euros.
