If you have access to the Magic Morning or going on a Non-Magic Morning day, you want to be at the entrance gates 30-45 minutes before the park opens.
If you have access to the MM and you are near the front of the entrance you want to briskly walk to Peter Pan.
On a Non-Magic Morning Day, once the gates you want to immediately head down Main Street and get as close to the rope as you can.
Once the park officially opens and the rope drops, you want to briskly walk through the castle and to the Peter Pan line of the right side.
If you want a less stressful morning on a Non-Magic Morning, get to the entrance 30 minutes before park opening.
When the gates open take your time down Main Street, perhaps take a few pictures with the characters at Town Square.
When the announcement starts for the park to officially open. head down Main Street. Skip Peter Pan, head down the path toward the Matterhorn (instead of going through the castle) and veer left, towards Alice in Wonderland.
Ride Alice first, then Dumbo, then Mr Toad, then Casey Jr., then Pinocchio, then Snow White, grab that Matterhorn FP that should be available in June.
Then ride Tea Cups, then Finding Nemo Submarines, grab FP for Space Mountain, use FP for Matterhorn, ride Autopia, Grab FP for Star Tours, use FP for Space Mountain, ride Astroblasters, Grab FP for Indiana Jones, ride Jungle Cruise, use FP for Star Tours... so on and so forth.
Anyways, basically save Peter Pan for when you have done everything else.
Use the official
Disneyland App and when you see the wait time for Peter Pan at 30 minutes, get in line. (Usually during lunch, dinner, and parade times)
