If at all possible, avoid routes to the front porch that are covered in crunchy snow and ice. Also, the fewer people making the trek to the porch, the better - I recommend less than three. Try to avoid paths to the door that may be more complicated than necessary. For example, if there is a 30 foot wooden ramp with a 90 degree turn in it that you must go up before even getting to the porch, consider aborting the mission and giving the toys to the neighbors. Or keep them for yourself.
Finally, if you've been volunteered by your commrades to be the one to stay and ring the bell (similar to being the wounded guy in a movie who stays behind to be eaten by the monster in the hopes it will buy his friends enough time to escape), and the porch light turns on before you get a chance to ring the bell, feel free to make as much noise as you want as you book it out of there as fast as you can. It doesn't matter if they hear you; In a matter of seconds they're going to open the door, see the presents, and know someone was there, which is the whole point anyway, right?
