SS, we as a family have only attended an abnormal MTTMM, due to a torrential downpour starting as soon as the "TT family of the day" told everyone that "they" were from Tacoma.

When the rain started, everyone ran for it, LOL, and the character meet/greet was done a little differently than normal.
So maybe I shouldn't even try to answer.
And on normal mornings I've never seen Minnie in her house; I've seen her outside of her house, though. On that MTTMM we attended, Minnie's house was used as a pre-queue area for Mickey's (oh the tragedy, it was so crowded we didin't find the fun interactive kitchen stuff!).
And those rides were indeed open.
Now hopefully someone with more normal MTTMM knowledge will chime in.
