We stayed in one of the deluxe garden rooms back in July 2009. The sitting area is definitely NOT separate from the sleeping area. Basically, the sitting area is the day bed/sofa which converts to a bed for a 5th guest in the room. You can not see the tv from the sitting area. The day bed was about 5 feet from the end of one of the queen beds. I don't think I have a picture to show you though. The deluxe rooms do have a better (closer) location & view than the standard rooms. Our room was 5107 which is on the first floor of the garden wing and very near the pool which was nice. It also had a patio - the 2nd & 3rd floor rooms do not have balconies.
So...if you have young kids and are looking for some separate space in a garden room, I would book a deluxe room and request a 1st floor room. Having a sliding door/patio was great for us to be able to hang out while the kids napped. Also, don't know if you have kids or what your situation is, but we were in need of more seperate sleeping space and found that the crib fits very well in the sink area of the bathroom. I know, not ideal if you have to use the bathroom at night, but it made all the difference for our baby to be able to sleep without our 3 year old waking him up!!! Hope this helps!
