From ewoks 2017 post:
"CR Atrium Club king rooms are request-only, and there are two of them as far as I know. Pretty difficult to score, but worth a request if it's definitely the #1 concern on your list.
The floor plan of Tower Club that was posted a few posts back is up-to-date. There are a total of 16 rooms. 2 king standard rooms (both MK view), 3 double Queen standard rooms (one MK view, two Bay Lake, no way to book one view or the other so it's sheer luck which one you get), and 11 suites. If you want to book any of these, including the suites, you'll have to call. Availability is never up-to-date online for the suites, and the standard rooms don't show up at all online. These rooms are all pretty pricey. With a young kid I'd almost always recommend Atrium over Tower Club for the awesome views of the Grand Canyon Concourse and monorail. Tower Club is a closed-off floor so you cannot see down into the concourse area, which is fun for anyone of any age, but especially kids I'd imagine!
Also, about the Tower Club king standard rooms: they are a maximum occupancy of 2 people. They do not have a pullout couch or anything like that like the Atrium Club rooms do."
