I was there solo last Friday from about 10:30 to 10:30. I don't know if it'll help much, but I can sort of give you an idea of my day and what you might expect to get done while you're there. The crowds should be similar. I'm a regular visitor, but I took the day much slower and more "touristy" than usual.
My first park was DL. I always get a FP Space Mountain first thing, so I headed over there. My FP was for 12:15 or something, which is a pretty decent time. Then I did Big Thunder (10 minute wait), Haunted Mansion (also about 10 minutes), Pirates (about 10 minutes again), Indy (single rider), and then the Jungle Cruise (5 minutes). By then, I could go back and get another FP for Space (for 3:30ish?). If you're getting there at noonish, expect the waits to be maybe 1.5x to 2x longer, if not more for HM. They'll get longer in the evening when the locals head over after work or school, so take advantage of anything between 15 and 20 minutes.
After that, I headed over to DCA. I got a FP for Tower of Terror and then rode it standby (10 min), then rode Monsters Inc. (walk-on) to kill the few minutes before I could get another FP for TT, then headed over to CA Screamin' and rode that standby. There's a single rider line, but it can be horrible (unpredictable wait and pushy people; there's really no semblance of order). Standby took about 15 minutes and I got to ask for the back of the train instead of being put wherever there was a single seat open. After lunch at Whitewater Snacks (at the Grand Californian), I went and got yet another FP for TT and then did the Animation Academy (drew Sandy Claws/Jack Skellington) and then used up my TT FPs and rode Soarin' once (single rider line).
That was sort of the "get things done" part of the day. After that, I went back to DL and took it easy. It was getting really crowded by then (about 4:30). I think I only rode Space Mountain (FP) and Winnie the Pooh (walk-on) in the 3 or 4 hours I was there. I mostly wandered around, looking at the Christmas stuff. Lines were considerably longer than they were in the morning. I waited until it "snowed" after the castle lighting and then hit Great Moments with Mr. Lincoln (which, in probably 150+ visits to DL, I don't ever recall seeing... and will actively avoid forever more (I do recommend the
Disneyland Story displays at the front of the theatre, though)).
I went back over to DCA to check out ElecTRONica after that. If you're a geek who grew up in the 80's (like me), it's probably worth taking a look. I found it loud and annoying with the nightclubby music and flashing lights, but I did like the Tron preview that they have in the Muppet theater (see point about being a geek who grew up in the 80's). I was going to do TT again, but the line was 45 minutes, so did the Animation Academy again (Tigger!) instead. Then I went back to DL (with the crush escaping the first show of World of Color) and rode Space Mountain (FP) again before calling it quits.
Tips:
Put off Fantasyland and the more "kid" oriented rides (Buzz, Nemo) until 10:30/11:00pm.
If you're staying until closing and want to shop, the stores on Main Street stay open for an hour after the rest of the park shuts down. Save the shopping and exploration of MS until then. The crowds die down and it's just really nice being on MS when it's empty and quiet. You'll also get an "extra" hour while the park is open to do attractions.
Touring Plans has a Disneyland app. It has pretty accurate statistical wait times and user who are at the parks post actual wait times throughout the day -
