At least one FT'er whom I trust to be "wordly wise" has good things to say about Sri Lanka, but my experience with a short visit a year ago was very ho-hum. We found ransport to be tediously slow, accommodation poor for the price, and no compelling reason to be there for a family with racks of different "been there" tee-shirts in the closets. But since other wise folks disagree, I'd guess that you can find things to enjoy there, but it may take considerable effort - friends on the ground, for instance - to do that. For us, it's a transit these days.
