Question : where is the best place to buy cheap all inclusive hawaii vacations?
and which island is least expensive, are there reasons for this?

Best answer:

Oahu is usually the cheapest to go to because it’s a major airline hub. Some airlines route all of their flights to Hawaii through Oahu. Apple Vacations is a pretty good site to check for package deals, but if you’re traveling with a group of four or more you might also want to consider booking a two or three bedroom condo and booking your flight separately. The larger condos are a pretty good deal because a two-bedroom unit doesn’t cost twice as much as a one-bedroom unit. You can save money on meals by preparing some of them yourself in the condo’s kitchen. If you decide to do that, check out http://www.vrbo.com.
