Near Hospitality House is a booking catagory, not a request at OKW. If that is available when you book, it would probably be what you are looking for. If it is NOT available when you book, you could request buildings 15, 16, 62, 83, or 64 and still be near HH. That being said, I wouldn't necessarily say that is your best option. It depends a bit on what size unit you are looking for and how many people will be staying. If you are looking at a 1 or 2 bedroom and will have anyone staying in the living room, you will want to request building 30 or above in order to have the second door to the bathroom without going through the master.
OKW has 5 bus stops, so you are always close to one, and ANY bus will take you to the Hospitality House area, becaue it's the last stop before exiting the resort. There are also 3 additional pools beyond the main pool.
