Travel has always been risky, but you might want to check if Aruba is still there before you fly out because it is hurricane season and anything can happen. Wind. Rain. Floods. Storm tide surges. Flying debris. Falling trees and limbs. Injury and death. Loss of power, water supply, emergency resources, transportation stopped or limited. These things and more have always come with the territory.
Seriously, Aruba should be just fine, but you might want to check the flights through hurricane prone areas.
