Autographs at Mission Space???

[Proud Newfie]

Hi

my friend is taking her daughter to WDW for the first time in October and I volunteered to print off autograph cards for her.

I have been checking the sites for who they may see and where, and saw that sometimes Goofy and Mickey are at Mission space.

My questions are
- do Goofy and Mickey still show up at Mission Space,
- if they do, do they sign autographs while there,
- and if they do, has anyone DISigned a specific mission space card for them?

thanks everyone
