If you can get summoned or portaled to Shattrah City, there are one-way portals there that anyone can use to get back to the major cities. Might be a good idea to set your hearthstone to Shattrah City first, though. That way you can hearthstone back if you need to return.
If someone I don't know asks me for a summon to Shattrath, I will gather two friends and summon - to the wildest part of Terrokar forest I can find.
