Basically, you can see the monorail from just about any standard view room (except maybe the ones ending in 13 and 25). But you will be better off requesting the rooms on the side overlooking the parking lot, Senses Spa, etc. You will have a great view of the monorail. From the rooms overlooking the pool, you can see the monorail, but it is over to the left, and you do not see it as long. You cannot make this request online. You will need to call Member Services. I would ask for parking lot side, upper floor. On the map, the rooms you would want end in 19, 20, or 24 (these are dedicated 2BR. If you want a lockoff 2br, you have additional choices, but they show on the map as 1BR and studio side by side).
