Thank you for the feedback! Now I'm even more convinced that any of these two options is great I read some more travel reports and I consider Yucatan to be more interesting in terms of nature, e.g. cenotes, jungle. I heard also that Cuba has the best beaches (Cayo Coco). Any advice regarding September weather in these to places, apart from hurricane risks? I know there are chances of rain in both countries, and Yucatan can be more windy this time of the year?...
