Wait til you get there to see what your vibes are. My kids are age 10 and we recently had a CL room right next to the CL lounge at CR; therefore, we would let our kids go get a drink out of the fridge and come right back to the room. To be honest, I would stand at the doorway and watch them. You have an older child, though, so it's hard for me to know how I'd feel with an age 12 child (I might be more willing). It's the different floor thing that I'm not sure about, but why not just wait til you get there and see how it feels. I remember seeing something in writing about the age of the children that must be accompanied by an adult, but I can't remember the age.
