On 10/2 they had many people lined up before 4pm waiting to get in but once in the lines moved quickly- I was there about 10 minutes to 4pm and just used my park hopper from earlier and then went to the rose garden to collect my wrist band and bag... since I was eating at the castle a few minutes later.
They did clear the park fairly well- and had a definite two way traffic of non-party goers exiting the park at 7pm and those arriving coming in like they were on the highway lol
I saw CMs stop many people without wristbands and few with them covered and direct those without to the exits. Saw none without later in the evening and there were many cm's checking the entrances to the candy lines and rides
