Here are a couple pics from immediately in front of my room. Notice in the first pic that the castle is above my son's head..... yes, it's that far in the distance. It's wonderful to be able to see the fireworks from your own room... but do think about how much time you'd actually be spending looking at that view. We ended up not spending much time at all looking at the castle, because we weren't in the room! The second pic is using my point and shoot's 4x zoom. Shot from the patio outside my room.
Sounds like you are leaning towards the GF or the Contemporary, but I wanted to show you that the view from the Poly side of the lake.
