Its difficult to know where to start. What are you looking for out of your resort? have a look here at Goa resorts( just noticed that are Sri lanka ones there as well for some reason!)The resorts in the south are a lot quieter than those in the north.
We have lots of hotel reviews here. Most people do not eat in their hotels so once you've picked your resort I would have a look at the restaurant recommendations on the sticky at the top of the page. Also, have a look through all the posts we have already. If there is something specific you are looking for use the search at the top of the page to help. ONce you've done that you are bound to have loads of other questions - so fire away!!
