We also have had a Chuck E. Cheese Night but we really had a positive experience. We didn't look at as a fundraiser, though... we consider it one of our family nights.
It was great because parents really had a chance to sit and talk and get to know one another while the kids were entertained. We packed the place! The manager at our location was nice enough to open a second register for our event to minimize waits. Also, they allowed us to direct customers who weren't with our group to use our line, maximizing our profit. I think the best thing about the night was that I DIDN"T HAVE A THING TO CLEAN!!!!
