We stayed in the spring of 2005 in a kid suite. It was located at the back of the property and was relatively quiet. Since it was our first trip to
Disneyland, we were very excited on our first morning so walked to the park. That proves it is doable; it's not what you want to do at the end of the day with all of the other walking though. It is not what I would describe as a walking distance hotel; it's a good ways down Harbor. You would probably want to use ART. The pool is a parking lot pool and we had other things to do so didn't bother with it. The breakfast was fine; the kids like the make-your-own waffles. The hotel provides waffle batter which you can pour onto the waffle iron yourself and cook up.
We returned to this property for one night in October 2009 because we needed a cheap place to stay before going to my in-law's timeshare. We had a standard room with two queen beds. The room was very clean and decent sized.
The walls were like paper though. I had a hard time sleeping as I could hear everything from the surrounding rooms and the street outside. We were too close to the front of the property, and the noise from Harbor bothered me a lot. We checked in in the late evening and the front desk staff was very courteous. The breakfast was as we remembered it. We drove and parked at Disneyland in the morning and spent a day there before going to my in-law's place in the evening.
I don't think I would return to the Comfort Inn. It wasn't objectionable, but we have found other places we prefer and we really don't like to be out of comfortable walking distance to Disneyland.
