I have always stayed in a standard view room. A few years ago, Disney reclassified room categories at the Poly, and the building I like the most (Samoa) was changed from standard view to pool view. I then started staying in Rarotonga, which has a lot of standard view rooms. Honestly, at the Poly, I don't think there are any bad standard view rooms. Most of their standard rooms overlook gardens. Some, like in the case of Rarotonga, can see the parking lot in the distance, but there is a lot of lush greenery and the monorail track between the room and the parking lot. I think one of the DVC buildings overlooks the parking lot, but if you are staying on the resort side you wouldn't be staying in that building.
Now, if you were asking about standard view rooms at the Yacht or Beach Club I'd tell you to pay more to stay in a room with a better view, but that really isn't the case at the Poly.
