In all current realistic plans the idea is to accelerate once and decelerate (if needed) at the destination. So not really doable to stop by on the way, unless you are going really slow - or its a part of the Voyage (e.g. multi millennia round trip where you replenish in every suitable star system along the way) provided your ship can handle the acceleration (could be assisted by built infra) and deceleration of a given "hop".
