Go to Hawaii during the off-peak season. The peak Hawaii travel season is from December through April, because that is when whales migrate to Hawaii for warmer waters, and also because most places in the U.S. and other countries are cold during those months, so people want to escape the cold weather for a while. Plan to go to Hawaii during the summer months, when tourism is slower and there are better deals to find.
Search for vacation packages on travel sites or through airlines. Many travel sites include airfare, hotel and rental car costs in one payment. Bundling the various costs can save you hundreds of dollars. Most major airlines also offer similar packages. To find the best deal, search the travel sites and airline sites and compare rates. Search early and often. You should also join email lists to be notified via email of any vacation package special deals.
Check websites that cater specifically to Hawaii discount vacation packages.
Consult a travel agent to see what kind of deals are available. Some travel agencies have access to package deals that are not available to the general public. The agency might also have a special relationship with hotels or resorts and can offer a lower, unadvertised rate.
Get a large group together or find one already established. Many vacation packages are even cheaper per person if you have a large group at take advantage of group rates.
