Early Entry days are now called Magic Mornings.
Magic Mornings (MM) are Sat, Sun, Tues, and Thurs. Guests with the MM privilege are allowed to enter DL one hour before DL's regular opening time. Most of the rides in Fantasyland and some of the rides in Tomorrowland will be open during the Magic Morning. It's a great way to start a visit!
This Saturday (DL's regular opening time is 8:00am) the Magic Morning will begin at 7:00am, and this Sunday (DL's regular opening time is 10:00am) the Magic Morning will begin at 9:00am.

Mickey's Toontown Morning Madness (MTTMM) is offered on Mon, Wed, Fri, and Sat. (MTTMM isn't offered on Sunday.

) Mickey's Toontown usually opens one hour
after DL's regular opening time, but guests with a ticket for MTTMM are allowed to enter ToonTown one hour earlier. MTTMM has a little show where guests become honorary citizens of ToonTown. I haven't seen it, but I've heard that it's kinda nice, but nothing great.
Hope that helps.
