I am considering taking a trip to India this fall and going on one of the two luxury train tours (Deccan Odyssey or Palace on Wheels). Does anyone have any experience, advice, recommendations, etc. on either of these tours? I am a single male travelling alone, an introvert, and don't really get into the partying scene. I am interested mostly in the culture and heritage aspects of a country when I visit. Any advice or recommendations would be greatly appreciated.

Thank you.
