6x10 Benroy windows

im planning on build a benroy that is 6' wide and 10' to accommodate a family of 4. A thought that just came to me is should there be windows toward the back where the queen size bed will be, or at least some type of vent for air movement. I am planning to have a/c but i would hate to have to run it just for air movement. i understand the windows in the doors will help with the front. Also if anyone has a moment they might be able to through something together in cad on how it might look with additional windows i would appreciate it greatly, my cad skills are horrible and are not seeming to get better
