I understand what you mean when you say that they need to build something at Disneyland before they build a third park. That being said, they should build something more fitting like a Frozen and/or Tangled ride in Fantasyland, a Princess and the Frog ride in New Orleans square, expand Toontown and/or Critter Country, do something in Adventureland if possible, do the most popular option of redoing an aesthetically broken Tomorrowland that still suffers from problems created 15+ years ago, or build a 9th land that will at least SOMEWHAT gel with the existing ones.
