still confused how to address this envelope?

[librarian]

Greetings!
I would like to get some suggestion on how to address this envelope.
This envelope is for Estelle Parsons , "August :Osage County" play. She will be appearing at Odrway Center (Feb.16-28).
Danieele Schumann the person who should get that envelope, and then forward to Estelle parsons.
Would this be a correct way to address my envelope:

To: Ms. Estelle Parsons
"August: Osage County"
c/o Ordway Center for the Performing Arts
ATTN: MS. DANIELLE SCHUMANN, PR COORDINATOR
345 Washington Street
Saint Paul, MN 55102
