I don't have pics, but we went through Grand Gatherings and asked for 4 rooms, two connecting (our immediate family of Dh, I and our 7 kids - one under 2), near Classic Hall/Food Court/Bus Stop, and near the parking lot (we drove).
We ended up in the Lady Building, in 1154/1155 (connecting), 1156, and 1157. The location was GREAT! We were only a few rooms away from the preferred section, without paying for preferred.
The Bowling Pin Pool was on the other side of the bldg, and therefore the laundry was only around a corner.
It was really quiet and we really recommend this location.
The last time we were behind the jukebox, two rooms back, and we liked that too, but this was even closer.
Here is a bldg. layout map, so you can see approx. where we were:

I wouldn't worry as much about requesting a specific room. Figure out what your priorities are, request them, and Grand Gatherings is excellent at figuring out how to fullfill them.
And don't wait until your ressie has been transferred to Pop or to fax (which you can do as back up, but I've never done it.)
Make sure you have your requests in when you make your original ressie.
Have a great trip!
I have a new Canon Rebel XTI and I'm ready to get some good photos.
