My fiancee and I are headed there in about three weeks for our honeymoon. We picked Roatan based on proximity and beauty. We are trying to decided if we want to scuba or snorkel. If we decided to dive we aren't currently certified. Should we take our classes in the US or in Roatan? Also, if we decide to go snorkeling, will we be missing out? We've heard yes and no, but would like more opinions.
