Pasting most of a comment I had left to a similar question in a different thread recently:
Here was my experience a few weeks ago using EE for
Disneyland as a Grand Californian (GCH) guest.
6:30, got in line for the GCH security gate into DTD. About 30 people deep in line. Probably mostly GCH guests but it is true anyone can use this line if they want to.
6:46, security gate opened. Probably 60 people behind me in line at this time. Single line splits into two and moves pretty quick. I’ve read that they might be running 4 security gates now instead of 2.
6:55, I have made it through security, walked at moderate (not run-walk) pace through DTD and have made it to the
Disneyland turnstiles (ticket gate). I am the 8th person in line for the turnstile I chose. There were people walking up to the turnstiles from the Harbor security entrance at this time, so they must have opened Harbor before 7 also, and some Harbor people are beating the first hotel guests to the turnstiles.
7:20, turnstiles open. Again moderate walk direct to the EE checkpoint on Tomorrowland side of Hub and then to the EE rope that is gating the path to Fantasyland. I am very close to the front here, maybe 1 person back from the rope. I reach this point at 7:25.
7:30, EE rope drops and I head straight for Peter Pan. Huge line behind me at this point. I choose not to run and just walk normally, so I do lose some ground here, but I’m still off Peter Pan with a big smile on my face by 7:45.
Given the size of that line that ended up at the EE rope at 7:30, my experience would be that you want to be close to the front of that line to maximize the benefit of EE. To do that, you need to be near the front of the turnstiles line, and to do that you need to be near the front of whatever security line you are going to use.
