Hi Greg. Welcome to Cruise-chat.
I looked up SZ in my well worn HAL brouchure. I am not sure what you meant by "Gtee" but SZ is a Superior Verandah Suite with a twist. I can't make specific comments on your room but it looks like the room and verandah are elongated at one end like an elbow. There should be a window as well as a verandah door.
You will have a great view if that is the shape of your verandah. Suite verandahs are wide and long with very comfortable plastic wicker looking furniture.
Make sure you have breakfast on your verandah at least once.
I have sailed on the Zuiderdam which is also a Vista Class ship. You will be very comfortable and well looked after.
Finally getting back on a Dam ship, Nieuw Amsterdam Nov'11 (My Mom's 80'th B'day cruise)
