2 days?

I'd go over to the
Disneyland section of the DIS. They've got a ton of stickies for first timers.
Disneyland still honor expired FPs.
I think Carnation Cafe is down. Blue Bayou is a must but you might not be able to get a PS. Disneyland's version of an ADR. Blue Bayou is inside the POTC ride. Get a water table.
Do not miss the World of Color. You can get a FP for it by Grizzly River Run in Cal Adv or buy a picnic or dinner package.
The Matterhorn is down for refurb. Don't miss Indy, the Tiki Room, POTC- it's far superior to WDW's. Fantasyland is very cool too. Oh and Disneyland's IASW is amazing.
Grab a FP for Indy then ride Peter Pan for sure and Dumbo if you've got small children.
Whitewater snacks at GCV makes the best nachos if you partake in that sort of junk food.

The lobby bar has a great vibe. DH and I enjoyed our nights down there after the parks. Napa Rose is supposed to be insanely good but we still haven't made it. Storytellers is a fun character meal and it's at the GCV. Disneyland Hotel has Goofy's Kitchen but we found the food and service last time to be subpar.
At Cal Adv, don't miss Screamin' or Soarin' or TSMM. They also have the Aladdin show, live, which is pretty cool. The Animation Studio is really fun too and perfect for a midday break. I think though, there's a lot of wastes space in DCA. The theme in Bug's Land is adorable- may want to skip the rides if you don't have kids with you but it's worth taking a stroll through.
