It's hard to suggest excursions unless we know the kinds of things you like to do. Water sports? Shopping? Sightseeing? Activity level? Any children accompanying you? Ports other than Barbados?
You may also want to search our previous discussions of your ports, by putting in the name of each port into the bar under the word "Find" at the top of the window.
We are happy to help if we have a little more information.
