Travel Plans to India

I have my Lonely Planet India (Lonely Planet India) and have input from friends on when and where to go in India. Top spots include Bangalore, Kerala, Mysore, Hampi, Jaisalmer (for a camel safari), Agra, Dehli, and Calcutta. So much to do. With the way things are paced in India (I was there ages ago) I think 3 months is the appropriate amount of time to travel to all these places.

The good news is that I have enough miles on Northwest for a free flight. I need to be flexible on the dates, but if it saves me $2,100, I can live with a little flexibility.
