we were at a different center than ACC (though we're in preschool at Ballston Children's Center, a sister school) but I can speak to the "cribs in the same room" thing. Our infant daycare had the cribs in a different section of the same room, and it was never an issue. Our daughter was in that room from 6 weeks until about 12/14 months and she was able to sleep, no problem. The kids gradually moved to similar/same nap schedules so they were able to dim the lights at those times. Very sensitive kids who have trouble sleeping under less-than-ideal conditions might have issues, though. (our daughter can sleep pretty much anywhere, as can I.)
