Last August, we were at MK and AK on both EMH and non-EMH. On the EMH at both parks, nothing special went on at the time the parks opened for EMH (although I wondered if they still did it at the regular park opening (but by that time, we were nowhere near the park entrance to notice. On non-EMH day at MK there was the character arrival by train (and the songs and dance), but that was all before anyone was allowed through the turnstiles (and the last thing that happened was that Mickey announced that MK was opened. Then as people were admitted, there were tons of characters available for autographs in town square. At AK, I don't remember much happening before the park opened on the non-EMH day, but when people were admitted, as mentioned on a previous post, there were CMs carrying critters around in cages and Wes Palm was around, as well as other characters (we didnt notice any of this on the EMH day). It seems like on EMH days, they are just trying to allow everyone to get to the attractions as quickly as possible, but on the non-EMH days, they seem to be trying to spread the crowd out. Some will always make the mad dash for Space or Splash Mountain or Fantasyland., but the goings on near the entrance will lure come to hang back.
