Hi Monty.
I am doing the Kerela trip in September and am looking forward to seeing this part of India. Did the Spirit of India trip in 2012 and this,was a great experience. Visited China in 2010 and this too lived up to my expectations.
If you visit the review section of the forum there are a number of recent reviews of the holidays which you might find helpful.
My advice is go for it!
