There were a couple of threads going a few months back that really helped me make my decision. One had people posting pictures taken off of their balconies, another had people posting their room #'s along with specific likes and dislikes.
I already had made my reservation, but I called back and updated my room request. I said I wanted Woods view (which I already had booked), north wing, even numbered room, with a Magic Kingdom/Castle/Fireworks view. I also requested bunk beds and non-smoking on the 5th or 6th floor. I think the 6th floor is all smoking, but I could have lived with it to get the room I wanted. In hindsight, the 6th floor would have had a better MK view, but I don't think you would be able to see the ground all that well. The 6th floor balconies are the ones nested in the roof.
I called the Wilderness Lodge directly in the morning 5 days before check in. That is when the hotels get our ressies. I verified that they had my room requests and even helped them out by supplying specific room numbers that I had read that met the criteria (like they needed my help

)
We were going to Blizzard Beach on the day of our check in, so we stopped by the WL at about 8 AM to register. Bell service took our bags, and we were given keys but not told our room #. When we returned from BB for a rest at 1:30, we called a number they had given us from one of the lobby phones. A CM gave us our room # and we walked right up and used our keys. I was excited to actually get the room that was #1 on my list! It was cool to walk into our room and see that it was exactly what I had imagined. (let me re-emphasis that the castle is not as close as what the balcony shot from room 5032 makes it seem - just so you will not be disappointed.) It only took an extra few minutes of prep time to secure the room we wanted, and it paid dividends all week long.
Hey, if you get that room, be on the lookout for the safe key that my son lost. I turned that room inside out looking for it. I even walked around in the grass under our balcony and couldn't find it. He was playing with it earlier in the trip and I didn't pay him any attention. I told the Mousekeeper and she said that security would come open it. I didn't bother sticking around, because I didn't think there was anything in there.
