The above estimates bring up the per person cost for the duration of the tour to 730 euros. In order to make the tour more affordable, for example to reduce the tour cost to 500 Euros, and assuming that 30 people will join the tour, we would need to collect (730 - 500) X 35 = 8050 Euros in donations from the Yogis. Other ways to bring down the tour cost would be to use yogi cars, hire a bus instead, or have fewer touring yogis.
