Placing beds

Hello everyone and let me just say thanks since now ,you always come up with great solutions! OK my furniture in MB is all placed great,thank you to those that commented. Now I need help with the guest/sons room. It's rectangular 12×16 with closets at end by entrance and the doors on the closets slide open so I don't have to worry about allowing to much room for that area. One closet is still my sons,but he is a Marine now but I want to leave his items their for when he comes home. In the meantime I have purchased a queen size bed for guest. His is full sized. One wall along the hallway which is 14ft long or so due to door. Wall across has two standard size windows. Currently there is a cedar chest in between windows that must stay in room and a chair by the window that is his and his small 2ft desk. So should I place the beds next to each other along windowless wall and across windows since he likes to look out from his bed or should I have one on one wall and one along other wall by a window? This is his first year and so mom's out there that know or even those that aren't in same position but can understand my promising to keep his things in his room can understand why at this stage of the game you want to see their things. It's just like when they go to college and you leave the room for them. If it becomes his career then I will not feel the need to save his bed in there and such because he will be our guest. I just want guest to feel comfortable as well and I have a closet for them to use as well as a chest of drawers. Sorry forgot to mention earlier yes it's a tall chest of drawers but small. OK so that's all. You guys helped me before so help again,please. Thanks.
