Flight costs: $876
There is simply no perfect season to visit Hawaii, as the Aloha State boasts of great weather year-round. They have so much to offer their tourists, and each island has its own events to look forward to. In April, they have the Hawaii Arts, Crafts & Food Festival which showcases their best local products. It is also worth noting how many free gorgeous beaches they have there. It feels like summer all year long.
