We are headed to T&C. I imagine it will be a "one and done" for us as well...most islands are for us (we have only returned to Nevis). There are too many islands that I still want to get to.
We did Long Island in the Bahamas years ago, that is more my pace for vacation. But, I'm up for a different kind of vacation...right now, I am up for ANY vacation since it's been over 2 years of not leaving the state. We will get to Bequia some day and I have my eye on the Plantation House.
