We've stayed there a few times. It is clean enough, and the rooms are pretty big. I'd say the pool is very large, compared to the other motels in the area. The walk is pretty short, maybe 7 minutes to the park. The main down side is that they charge for parking, so if you are driving in, be sure to factor that into your price.
Since we've discovered the Hojos (thanks DM) that is the only place we've stayed, but I'd consider going back to Anaheim Plaza Hotel if I couldn't get a great rate at the Hojos.
