I didn't find it to be that overly big. We stayed all the way at the end of one of the roads, and I had no problem to talk back to the main area of mug refills.
However, you need to keep in mind that it is a DVC resort. You don't have the same need to go to the main building all the time as you may at the other resorts. There are multiple bus stops around the resort, so you never need to go the main building to get a bus (except for DME). And you can take a bus back to the hospitality house, so no walking is ever need except to the bus stop. However, you should either have laundry in room, or nearby (if in a studio), pools are at multiple locations on property, as are ice machines and there is a second snack area. The CS location at OKW is a bit on the thin side, and since you have at minimum a kitchenette in your room, plenty of people choose to bring their own food instead of going over. Even at check in, bell services will help bring both you and your luggage to your room if you don't want to walk.
