There are few "Outstanding" views at OKW, there are also few "Awful" views at OKW. As far as view requests being met, it really depends on how fully booked the resort is when you check-in. We usually go to OKW in early December and Early June. Usually, but not always, I am given a choice of 2 to 3 general areas of the resort when we arrive (normally about 9:30 or 10am). If the resort is fully booked, you may not have a choice.
For me, the worst views so far have been bldgs 28 or 29, with the best views being 30 and 31, though I have not been fortunate enough to stay right along the canal. Even with the relatively "bad" views in 28 & 29, the rooms were fine and overall were a good location for us. The overall enjoyment of your vacations to WDW should never be contingent upon the view from your balcony.
