In my opinion, no one should be up walking around to do anything in a motorhome/class C especially children. Everyone should be belted in except when the vehicle is stopped. We do not travel with children but can get to the bathroom, fridge, and bedroom with our slides in. We always try to find an end spot in a rest area so we have more room. We see lots of slides deployed in rest areas. If you can find a place where one side is over the curb at a Wal-Mart, you can usually safely pull out all your slides and stay within the confines of the parking spaces. Even just a walk around a store might burn off some of that excess energy.
