We liked our stay in Dec '07, especially being on the first floor with wood floors. I've never looked at a carpeted hotel floor favorably since then!
It was just a pleasant place with nice employees.
When you walk to the parks, we went to the intersection (turn left as you get to the sidewalk), cross Katella, and go towards Paradise Pier Hotel. Stay on the right side, and when you get to the Grand Californian, go in the big front doors. As you enter, go to the left down a long corridor, and that will eventually lead to automatic doors on the right, exit through those, follow the path, and you'll come out in Downtown Disney, right next to Sephora (and across from Haagen Dasz). Turn right, and you'll be at bag check and the esplanade quickly!
