Kolkata Airport to city transport.


Gastro traveller..
We are going to kolkata on a family trip on next 20th. Our group includes 2 senior citizens and one kid. We have booked accomodation at Pretoria street area. As none of us apart from me ever visited the metropolis before, most in the group are scared of getting lost if we hire 2 separate taxies. They are insisting to find out a vehicle that will be able to transport 6 of us together. Is there any such option available? If yes, how much may be the cost?
