I just left Windmills Plantation and I am already planning a trip back.
Windmills is pretty near perfect in my opinion. There are only 8 guest rooms, all with lovely views of the sea. The buildings are classic (yet whimsical) and the rooms are very well appointed. The grounds are well kept with a big two mile private beach (in addition to the rest of the little island). Snorkle right off the beach and collect shells galore.
We dived a few days, but there is plenty to do (or not do) besides diving (kayaks, etc). There are plenty of good beach loungers, hammocks and special places to relax like the lovely outdoor living room (rattan couches and big club chairs). Jim and Sharon are your hosts and they take care to make your stay special. The food is INCREDIBLE - everything is made there (including the 10+ desserts offered each night) and special needs are no problem (veggie, lactose intol etc). It was absolutely lovely and peaceful. Highly recommended by a picky New Yorker who has stayed on many islands in the Carribean. Book with confidence.
