You may have already contacted David's about your room request but I can tell you with 100% certainty their guests make room requests all the time and it is within their policy to have the owners who make the actual reservations request said room vicinity requests with member services.
I'm an owner at OKW, have been since presale days and I deal with the resort on a constant basis about what is going on. I have some friends that are castmembers that have helped me get alot of knowledge about the resort. I have friends that work for David's so I can confirm on both sides of the matter.
The official Hospitality House category buildings are 11, 12, 13, and 14, are directly across from the Hospitality House. Also, 23, 24, 25, and 26 are just down from the Hospitality House on Peninsular Road. You'll see in the map below Blue circled buildings are the HH category buildings. Outside of HH 15, 16, 62, 63, 64 are the closest buildings to HH.
62, 63, 64 are also the only buildings at OKW with an elevator.
For a quiet balcony I would recommend buildings 51 through 54 as they back onto the fairway and are far enough from the road you shouldn't hear to much noise. 33, 36 and 37 are also viable options for a quiet balcony. Avoid 45, 46 and 55 as they overlook the Sassagoula River and you'll hear the ferry's throughout the day.
Here's a little information about the building style layouts at OKW.
OKW has no Dedicated Studios or Dedicated 1Bedroom villas. There are 274 Dedicated 2Bedroom villas and 230 Lockoff 2Bedrooms (comprised of a Studio and connecting 1BR) and 27 3 bedroom Grand Villas for a total of 531 Units / 761 Max. Available Rooms.
