I got my first postcard today too. My first step will be looking through this thread to see what people have in their signatures that match the clues.
Is the Sunday night at 7 an
MVMCP party?
They may be staying at Animal Kingdom?
I believe the frosted is the bouncing Mickey?
And no idea on the last clue yet.
I'll be back later to do some investigating. This is so cool. I'll be sending my cards this afternoon.
