First of all, no matter WHICH bus stop we are near at OKW, our rental car sits in the parking lot unless we want to go visit a restaurant at one of the other resorts. For park travel, we always take Disney transportation. It's faster, easier, and OKW has great bus service.
As for Hospitality House. While there are some aspects of that catagory that are nice, there are also some negetive aspects to it. For example: anyone who is planning to have someone sleep on the pull out in the living room will necessarily also have them traipsing through the master bedroom to get to the bathroom. These are all units that do NOT have the extra door to the bathroom through the laundry. Also, if you are not able or eager to do much walking at all and you happen to get the units directly across from HH (11-14), you could be either staying on the bus to the bitter end when coming back into the resort, or getting off at Penninsular Road and walking back. Frankly, I have never seen any real advantage to the HH area. We have stayed in buildings 13 and 14, and while they were convenient to the last bus stop, they also required the extra walking at the return end. I usually have very little reason to go to HH once I am checked in unless I need something from the store, or am planning on dining at Olivia's. For those things, any bus gets me there quickly from any of the outer reaches of the resort, or I can choose to walk. Frankly, I much prefer the buildings over number 30 where there is the extra door to the bathroom. I find that to FAR outweigh the convenience of the being near HH. I live with that little issue the whole trip, where I might only need to get to HH a couple of times in a trip.
