I'm making a quest where at a certain point a portal opens up to another area. It is a door type object. I want to make an NPC on the other end of the portal to decide to walk up to the player, but use any doors that makes the shortest route (ie, the portal). How would I do this?

set an activation area at one end of the portal, and then just move him to the other marker?

Just use the mere Travel template

Location of the Player

AI is predetermined to cross the most obstacle-less and shortest path

Thanks denmax, sometimes the simple solutions are the best.

Actually, the travel package appears not to be working. He will walk up to the player if the player is in the same room as he is, but otherwise he doesn't do anything.

Travel is loaded when it is executed, and doesn't reload it a second time unless re-executed (AI packages are re-executed with change cell, wait and sleep, or when a conditions returns false for a moment then returns true after a while).

If Travel doesn't work, then Follow. If that doesn't work, then scripts. May I ask, what conditions did you place?
