With 2 days I would absolutely recommend MaxPass! The exception: If any of the kids aren’t big enough for most the rides with height requirements (40" tends to be the magic number) & will sit most of them out. In that case you’ll have a built-in FP runner, so if the adult staying back with non-riding kid(s) is happy to be the go-getter & taking the extra steps to grab the next FP, it’s an easy way to save some $$ to put towards snack/souvenirs. In this case you would also get to use Rider Switch for the non-riding parent to get a turn (and would get to take 2 other rides with them who could include anyone from the 1st group that would get a 2nd ride in, those lucky ducks!). Rider switch will slow you down if both parents want to do everything but if you have more questions on this, ask away!
I also recommend arriving as early as you can. At least 45-60 min before rope drop (park opening) to take advantage of the lower crowds in the mornings. You have until about 10am before crowds start coming in so hitting the parks hard for that prime early morning touring gives you a huge leg up. Leaving you the rest of the day to use up FPs and if time allows enjoy show/atmosphere.
I once upon a time made a list breaking down Disneyland attractions in categories of their must-do’s bc they are Unique comparing them largely to WDW. You can find that in my response here (the lists starts mid-post so scroll down to Must-Do’s Unique to Disneyland Resort to get started on it).
So if you haven’t already come across that, take a look. My responses to all of it are still current (the only minor update is that we have tried Jessie’s Critter Carousel now as it was open on our last trip & as I expected my kids did love it).
ETA: I scrolled through the list and I do mention Soarin’ Around the World BUT the version that will be playing on your dates is Soarin’ Over California which is a throwback to the older version of the ride & one of my all-time favorite attractions so having it be this limited-time version puts in the Must-Do category (for me). I like the newer around the World version just fine, but don’t love it the way I did the original California version & it’s nice to have it back, even if just temporarily.
