There is a cbild care center staffed with caregivers, they only take a certain amount of kids, but if they are full when you get there they will call your guide when spots become available. We did this, just this past weekend. We have a four year old and an almost 2 year old. They gave us a beeper and when she needed a diaper change, they beeped me, I changed her and brought her back. It was great.
Two years ago when we bought our original contract, our son was just turning 3 and our daughter a few months old. Our son refused to go in the center and the baby was too little, and it made for a very long & trying process trying to do the closing with two restless kiddos.
