We stayed in building 4 years ago and had a fabulous view. We were in a 3-bedroom unit on the top floor and could see all of WDW from our balcony. We got 2 fireworks shows every night! (I tried to post a few images, but, since I'm a newbie, I can't yet.)
Last year, we stayed in a Presidential Reserve unit in building 3. Our view wasn't stellar, but we had access to the Presidential lounge which had a phenomenal view of the parks, also.
We've also been there and been on the first and second floors facing the parking lot.
It's definitely a crap shoot, but there are some great views there.
