Where should we go for an October honeymoon?

Tobago is great, its pretty small though but still has good resturants and things to do. I visited in June/July which is low season there in terms of tourists. It was relatively quiet, the beaches weren't crowded and on boat trips we were often the only ones on them. Theres plenty of little stalls selling lovely shells etc and the fresh fruit is amazing. There is also a good shopping mall and you can take a tour in the rainforest. The beaches have plently of watersports available and there are trips to see wild dolphins and turtles. Lots of tropical fish and coral, snorkling is excellent, sea is warm.
