To answer your main question: No, Aurora does not seem to be featured any more prominently at
Disneyland. I've seen Cinderella at more locations and she always seems to have the longest lines.
Goofy's Kitchen at the Disneyland Hotel has characters for all three meals, almost always including one or more princesses. We ate several meals there last week and saw Belle, Jasmine, and Alice. On a previous trip Snow White was there. So maybe Aurora is there sometimes as well. I'm not sure how far in advance they know the characters, but worst case you could make a PS, call an hour or so beforehand, and cancel if you're not interested in the characters. An extra bonus is that one or two times during the meal all of the kids get to go up and gather around all of the characters for a dance. If you're not staying at one of the Disney hotels, it will be about a 10-15 walk from the park through Downtown Disney. You can also ride the monorail from Tomorrowland (I think that's the one) to the far end of Downtown Disney which puts you very close to the Disneyland Hotel.
On two different trips, last week and last Februrary, every day we were in the park Cinderella, Belle, and Aurora made several appearances throughout the day in front of the castle for pictures and autographs.
As previously mentioned, the shop just to the left as you exit the rear of the castle has a story time a few times a day with different princesses. After the story, kids line up for pictures and autographs. You can check-in first thing in the morning for the schedule. We've seen Belle, Snow White, and Cinderella here. Don't know if Aurora every does this. VERY IMPORTANT: Don't expect to show up at the end of the story and get a picture. I've see quite a few little princesses walking away in tears because the line got cut off before them. (Making that cut must be the worst job in the world.)
Finally, there's another place (I think somewhere in ToonTown), where there's a room to meet the princesses at various times of the day.
Here's one idea for getting "special" time with Aurora. During a previous trip, we just happened to be the last person in line to see Cinderella at the location in ToonTown. After taking pictures with Cinderella, she took my daughter's hand and walked with her through the park to her next "gig". Needless to say, this was one of my daughter's highlights of the trip. So, when you do find Aurora, you might want to ask the attending CM if you could be the last one in line when they make the cutoff. At the minimim, you'll probably get a little extra quality time. But you may end up getting a bigger surprise like we did.
Good luck.
