Where you're going: Aruba
This sunny, friendly, Dutch-accented island is known for diving (over 40 major dive sites, including shipwrecks and coral formations), hiking and nature trails (more than 20 percent of the island is a national park), hot nightlife (no need to drive—just hop on the Kukoo Kunuku party bus), and of course, perfect beaches with soft, white sand and turquoise waters.
