Peterd,
We actually requested the one floor since we have 3 1/2 year old twins and would have preferred keeping them on one floor but the two story was fine. It was room 5035 and it was located in the building with the pillars. We really loved the location! The layout was really nice with the kitchen, dining, tv area, and master bedroom on the main floor. Upstairs had 2 bedrooms each with a bath. One of the bedrooms upstairs had a balcony. The other had a balcony looking over the tv area. Not sure what the point of this is because the light from downstairs shines in to the room if people are up watching tv downstairs. The laundry was upstairs also. We really enjoyed the GV. If you have any more questions ask!
