Tobago and Barbados

My wife and I are travelling for five nights in Tobago and three nights
in Barbados, in March 2004. We like diving, snorkeling, hiking, walking
and swimming. Also tennis players and avid eaters.... (good thing we do
all the walking etc).

Any thoughts on places to stay, especially in tobago, much appreciated.
We aren't really resort types but could do a low-key one, and like
cottages or bungalows, etc. We want less noise and more nature.

All suggestions much appreciated.

John
