Mount NPC and then run to spot to do quest

[Ruinit 11]

Does anyone have an example of this quest http://www.wowhead.com/quest=27000/learning-the-ropes ?

You are to mount a horse and scare some spiders. I set up and interactwithnpc to mount the horse but there are 10 horses in the area and it keeps trying to interact with them? It seems to not understand that I have already done this step.

Seems like there should be a run once setting or something so it would move to next objective.

Any help would be great
