Be sure to check out any travel warnings before taking the plunge with your wallet. For instance, although tropical cyclones may occur throughout the year, the South Pacific Tropical Cyclone Season is during November to April. I imagine you can find some really good deals during this time, but then you may encounter inconveniences of delays. However, you may also be subjected to dangerous conditions before and even after the storm has passed. For more tips on when to travel to certain destinations, check out http://travel.state.gov/.
Other things to keep in mind are vaccinations and other health precautions that should be considered. You can always check the Travelers’ Health page of the Centers for Disease Control (CDC) website at http://www.cdc.gov/travel.
