Best company tours doing Golden triangle (New Delhi)

Hi,

We are 4 spanish friends on their mid-thirties who are planning to do the Golden triangle (Delhi, Agra and Jaipur).

We are looking for a company organising this tour, including the transport among the cities.

We are not looking for a private tour, but to be with other people in the group (preferably people of our age, or at least not families).

We heard Trinetra is good but they don't reply to our e-mails.

Is there any company you could recommend us?

Many thanks for the advice.

We also would love to meet nice people to hang around in Delhi, where we will from 19th to 21st February Protected content .
