Hi
I have just got back from Tobago and I have been many times, I certainly did not feel threatened when I was there in Feb, just be sensible and don't go off to a deserted beach by yourself.

I book with a tour operator that offers greaat locationa all around Tobago. I did a 2 centre and I had a great time.

check out www.fleewinter.com/tobago/index.php as I find they have the best selection of accommodation.
