Offsetting transform.position by local rotation

I'm using a script to move my player object between exterior/interior setpieces. I want to move the player from Trigger A to Trigger B, but offset Player position a few units on Trigger B's Z axis so the player doesn't arrive in the trigger. I'm not sure how to transform the local rotation of Trigger B into an offset in global space, though.

Code (CSharp):

1.  
2.     private GameObject Player;
3.     public GameObject Destination;
4.  
5.     // Use this for initialization
6.     void Start ()
7.     {
8.         if (Player == null)
9.             Player = GameObject.FindWithTag("Player");
10.     }
11.    
12.     void OnTriggerEnter(Collider other)
13.     {
14.         Player.transform.position = Destination.transform.position;
15.     }
16.  

 

Code (csharp):

1.  
2. ... = Destination.transform.position + (Destination.transform.forward * someScalarValue);
3.  

(always getting my axes mixed up; replace "forward" with "up" or "right" or negatives of them to get whichever direction you need)

 

perfect, thanks so much!
