Stayed at this hotel for two nights before moving over to the Grand Californian.
The Fairfield is an adequate motel with exterior corridors and pleasant decor. The front desk staff was extremely helpful and went out of their way to make us comfortable. The room had two queen beds and a split bath with sink in the room and toilet and shower in the bath. The room was recently renovated and looked fairly crisp and clean. I did notice that the walls are extremely thin so you hear absolutely every sound your neighbors make. I also found the beds to be rather hard and uncomfortable. I was glad that we were only staying for two nights.
There is a McDonalds and a Millie's Diner in the parking lot. Mimi's Cafe is right next door. Ten minute walk (or less) to the Disneyland Main Gate. Location, Location, Location!
Be advised that if you use Disneyland Airport Express to get to the hotel from SNA or LAX the bus will drop you and your luggage unceremoniously at the curbside in front of Millie's... it's a long walk with luggage and a tired kid to check in!
