<font face="times" size="+0">I don't think there is such a thing as a Dedicated Studio at OKW. All studios are lock-offs, IIRC.
I studied my pics again, okay I changed my mind, there's a little thing that looks like it might be a safe. Except in my pic it looks like a piece of white paper w/ a lot of small print text on it that looks like safety instructions for the fire extinguisher or something. Unfortunately, in my pic there is a hanger w/ the Yellow/white Disney laundry bag that blocks the edge of this white square, where perhaps the key to the safe is hanging? So I can't tell for sure from my pic. I certainly don't remember using a safe though.
But the safe could've been there, and I just didn't think to use it.
Did you try calling the OKW front desk to inquire?</font>
