It all depends on your preferences! (And by the way - We just Love OKW!!) If you want to be close to the lodge and main pool, you can request that area (we had a studio once near there -- it made the bus trip convenient, and dining at Olivia's was a snap...My kids liked the lodge activities, too.)
Most of the time, despite any requests, we invariably ended up in Turtle POnd (3 trips spent there, each time a 2 br). Nice thing about it was that we still had a pool right there and playground and hot tub, and the bus stations weren't too far away. Personally, it's hard to find a "bad" place in OKW, to me, because the buses loop all over the place so you're always near transportation. HOWEVER -- I can't recall if they are still renovating parts of OKW. When we stayed there Jan 01, the buildg next to ours was getting a "facelift" of paint and such. If you can find out if any such work is going on, look at the OKW map and then pick a spot away from it! (haha) Also check to see if any pools are closed or planned for work -- bummer to be near a poll you can't use (if pools are of interest to you...)
