And to clarify a bit further:
For on site guests, early entry to DL is called EMH (Tuesdays, Thursdays, Saturdays -- unless Disney changes the days, e.g. CHOC Walk weekend). The one hour early entry applies to FL and TL only. For DCA, early entry is called EE (Mondays, Wednesdays, Fridays, Sundays -- unless Disney changes the days). For DCA, the one hour early entry is usually for the whole park, unless otherwise stated.
MM only applies to 3+ day tickets, purchased in advance (not at a ticket booth), and not to military discount tickets. One MM per 3+ day ticket and only for DL.
