"Target" vs. "destination"

Target is something you try to hit; a mark you aim at when shooting, or figuratively a goal or objective of your actions. Destination is a place where you want to arrive. In both of your examples (Hawaii and the video store), I would go with destination. I would only call Hawaii a target in the context of war, or if it were a node in a directed graph. In the context of flying by plane, target sounds especially scary, because it brings 9/11 to mind.

Generally, when you are yourself in movement, the object of your movement is referred to as your destination.

When you are throwing or shooting something, the point to which you are aiming is the target.

Destinations are things you want to keep intact when you get there; targets are things you want to perforate or explode.
