We are going on a Southern Explorer cruise in October for our honeymoon. The stops are San Juan, St. Thomas, St. Kitts, Grenada, Aruba, and Bonaire. I was wondering if anyone knows what the weather is like in these places in October and if there are any good places to go scuba diving. We did the discover scuba diving in St. Thomas last month and are looking at doing the same type of thing on this cruise. Also, does anyone know any other good excursions for these stops, or any excursions to avoid?
