One Indore rental listing currently quotes approximately ₹22/km for a 12-seater Tempo Traveller, ₹24/km for 16-seater Tempo Traveller , and Urbania around ₹30–35/km depending on seating. For Char Dham specifically, the operator says Urbania is charged on a per-day basis rather than per-km. For a Char Dham Yatra, I would recommend Urbania over a regular Tempo Traveller if elderly people are travelling, because of the better seating and comfort.
