Looking to plan a "last time as an only child family/baby moon" in the early fall to somewhere warm and beachy. Except I forgot about zika...

I looked at the CDC map and the following seem safe (or on the "no longer present list):
- Bahamas (just went Nov. 2016)
- Bermuda (just meh - might not be as warm then)
- Cayman Islands
- St. Barths

Suggestions - either other places to consider (flying from NYC) or sell me on one of the above?
