I suggest add Sunderban to it (You can visit Bangladeshi part too)....some people say it is boring but if have luck it will be a life time experience. You dent get the opportunity to see a maneating tiger from short distance and come back to tell the story.
One of my friend who is in wildlife photography took a picture of Sunderban Tiger from few feets distance which drew him in some official trouble....I will try to post that picture if he permits....
