As far as value hotels go, Pop is probably the best. It has been/is being renovated (did you get a reno'ed room?) and is therefore the freshest. I stayed in a reno'd room for part of my Marathon trip and the lighting, electrical outlets, safe and other amenities were better in some respects than those at AKL, where I also stayed.
For overall resort ambiance, you could upgrade to a moderate. PO-Riverside is nice. But they are not cheap rooms-even with any meager discount Disney might come up with. I balked at paying over $200/night for a moderate. You might see what TA's are offering. Seems like it's always Coronado Springs--don't know what the constructions status would be for that time frame.
