Since this thread has been resurrected, I'll add one more place that hasn't been mentioned... Montserrat. Doesn't fit Carol's requirements but maybe for others. Last month, I went to Monserrat for the 3rd time. All arriving by boat but you can get flights from Antigua. Montserrat is the most wonderful place, beautifully green except for the bits damaged by the volcano. Very little to do but, if you like peace and quiet in the Caribbean, I don't think it can be beaten.

The people are incredibly friendly. An example... Before we arrived, we had tried, but failed, to contact the tour guide we had previously used 12 years ago. When we were in C&I we asked if the customs inspector knew him. She did, and yes he was still working. She asked other staff if anyone had his number, someone did and they called him for us. No reply. Oh, well we thought that was the end of it. Two minutes later as we were walking back to the dinghy dock, she came running after us (always worrying when officials come running after you) but she just held out her phone and said "I've got Joe for you". Imagine any C&I person doing that for you, in any other country in the world! Montserrat is wonderful.
