After many bareboat sailing trips in the BVI, we've decided to explore the Exumas out of Nassau. From all the YouTube videos we've watched, it seems much less developed than the BVI (which in truth, is why we wanted to go). We go through a LOT of ice when in the BVI and appreciate the vendors who stop by almost daily to take our trash and replenish our coolers with ice. What have others done to keep their adult beverages cold when ice might not be available most days?

Thanks in advance.
