We've stayed in 7001 and 7002 which are the closest two Bungalows to the MK boat dock (so the furthest to the left when standing in the resort area looking out to the water). A fairly short walk to the pool and GCH, and one thing I liked was that when you go to the MK you can watch out from your balcony for the ferry approaching, and then you have time to get to the boat dock to get on that ferry. We had not made any location requests so it seems that Disney considers that end to be the most desirable as it put us there by default both times. The advantage of the other end would be that you are closer to the TTC for going to Epcot.
