it's Monday, Wednesday, Friday and Saturday
the logistics are this: the required voucher gets you into toontown one hour before it opens; toontown opens one hour after the rest of the park opens; therefore toontown morning madness should start when the park officially opens.
so in this case, toontown would open to the public at 9, so the morning madness is from 8-9.
not sure when the ceremony itself takes place. last time i did it, it was around 20 minutes or so past the hour? before that, it used to be like 45.
