For Gangtok take a whole cab (small) for sightseeing 4ppl can be adjustable it will cost you around 2500 per day and for Darjeeling also you have to book a whole cap (small) for morning sightseeing (Tiger hill) they may charge upto 2000/- and for other day you have to take different cab which will charge around 2500-3000 per day.
Never go with tour operators like "Denzong Voyages and Travels". Better to book daily from the hotel itself
Terrible experience with Anisha Tamang and denzong. Premium priced and below par service. Absolute disappointment/ We paid an amount of 30k towards transportation and white water rafting. Tour was for 3 days darjeeling and 3 days gangtok. As per terms we should hv got an innova with luggage carrier for the tour.
Please avoid Anisha Tamang and Denzong. Better don't go through agent and use the travel booking available at the hotel side
