夏威夷 has amazing nature beyond just the beach.

加勒比海的岛 are really boring in comparison. Hawaii is not just Wikiki beach. The island of Kauai, for example, has the most number of hiking trails that allow you to get to hidden beauty like Napali coast. These hiking trails go through lush tropical rain forest, interesting volcanic areas etc. For a nature lover, 加勒比海 is no match to Hawaii.
