For guides and drivers, tips are an important part of their income. But it is not easy to give a number per head. This amount can be important if you are a big group and very small if you are two. You should therefore take into account different factors (number of participants, skills of the guides, etc.) to prepare a reasonable tip. We therefore advise you:
10 – 20 usd / day per group for the guide
5-10 usd / day per group for the driver
One usd / time per group for hotel services
