So I was looking on the address page for Debby Ryan, and saw two addresses, and I was wondering which one would have the fastest response. I also saw people getting successes from the Disney Channel address, but I've also heard that Disney isn't good at passing on fanmail. Which of the three should I use?

Debby Ryan
Kritzer Levine Wilkins Entertainment Llc.
11872 La Grange Avenue
1st Floor
Los Angeles, CA 90025

OR:
Debby Ryan
CESD Talent Agency
10635 Santa Monica Blvd.
Suite 130/135
Los Angeles, CA 90025

OR:
Debby Ryan
c/o Disney Channel
3800 W. Alameda Ave.
Burbank, CA 91505

Also, on this address, I've seen people leave out the W in the third line. Does it matter if we put it there or not? I've read in magazines (especially M) and they didn't put the W, and on others, they did.
Thanks!!
