In the floorplans I've seen, the junior suite is two connecting rooms. One room has a king or two doubles (not sure if you can guarantee the king) while the other has an arm chair and sleeper sofa. There are two bathrooms, but no kitchen facilities, just the normal minifridge and coffee maker.
I'd be sure to check before booking to make sure this info is accurate--I have not stayed in one, just seen the floorplans online--maybe on Deb's site?
