I bought the Bradt guide because the lonely planet and rough guide to Sri Lanka are so out of date but I had to return it to Amazon as its hopeless! It only lists 2-3 places to stay for each location and they are all hugely expensive ($100-500!!). There are hardly any budget accommodations listed. It also had nothing on whale watching (for which Sri Lanka is famous), a tiny section on diving which contained no useful information at all. Also, when i looked up the elephant orphanage in the index, it gave me a page number, but whilst browsing the book i came across much more info on the sanctuary on a totally different page - i never would have found this info otherwise!
Totally useless book - don't bother.
