I am taking a trip to India for the first time. I will be in New Delhi for most of the trip -- also planning shorter trips to Agra and Jaipur (and Chennai for business).

Will one day in Jaipur be enough? I am thinking of taking the train from Delhi which arrives at 10 am and departing the next day on the 6 pm train back to Delhi. Is 2 nearly full days enough to see the major sites in Jaipur or should I stay for another day?
