I'm about 45 days out from my trip and just made PS for Chef Mickey's last week. About the only character breakfast I'm aware of that you have to call at 7am 60 days out is CRT.
I rang last Thursday for a ps for CM. Got it no problem, for the exact time I wanted. It is for our trip in October so I don't know if that makes a difference.
I am beginning to suspect that dinner is a little tougher at CMs than breakfast....there are lots of character breakfast options, but few dinner options and a lot of people make CMs a first night tradition.
