Romance is about to take a dive. One week after the full moons in September and October, the corals surrounding the Caribbean’s Curaçao spawn, which is to say, they reproduce. See this rare occurrence for yourself via scuba with Curaçao Sea Aquarium biologists October 2-9. You can also take part in coral research, biology sessions, and underwater photography lessons. 011-5999-461-6666, www.curacao-sea-­
