That seems as though it could be solved by making very short trips back and allowing the local gravity to continually correct your velocity and positioning until you reach your destination.

yes, but you need a lot of energy to move some matter in a single jump, so more jumps mean exponentially more initial energy because of something akin to a "time-rocket-equation" (you need to bring more mass to get energy but that means more mass or spending more time in a place to re-accumulate it).
It's a fun idea though, thanks :)
