What can you tell me about Tonga? I'm not a sailor, but I do like boating, fishing and snorkeling. Is Vava'u where I should consider? What about the boating off season. Is it somewhere we could live year round without feeling isolated? What about the cyclone season, do the islands become flooded? Where does everyone go when one approaches? Do they go the biggest island in the group and hunker down. I'm thirsty for information on everything about Tonga.
