It is definitely not a plan that I would recommend to anyone wanting to enjoy more than rides & Twitter on their DL day!!
But because it was a challenge we were chasing the adrenaline rush kept us happy to closing & beyond so I wouldn’t say it wasn’t fun.
DCA is actually a lot easier to knock out in one fell swoop & even though it has EMH for your one day the footprint of onsite guests who A) have access to it & B) actually get up early enough to utilize it are super small so starting there isn’t a big disadvantage. And if you are ready to line up for regular entry an hour before (so when EMH starts) you’ll be let in by 30 min before & the line for Soarin won’t be closed off to just EMH guests so you can get 1 ride in before RD. More importantly though, you’ll be able to obtain your first MP right at 7:30 & start getting up on that game.
We followed Disneyland Daily’s Big Kid’s Plan with MaxPass for our challenge day & it worked quite well! It includes every single attraction so if I had just one day, there’s a lot on this plan that I would skip (Goofy’s Sky School, SS Swings, Jumpin Jellyfish, Grizzly River Run and probably also Golden Zephyr and Pixar Pal Around). Then in the plan where Casey mentions to grab a 2nd Racer’s & 2nd Incredicoaster FPs I would start grabbing DL FPs (Haunted Mansion Holiday & Space Mountain would be my choices, Indiana Jones is a good choice as well if either of those don’t appeal to you for some reason).
