there are maps of the resort available in other threads and from looking at it we decided we want 50's building 2. we wanted a lake view (partial anyway), and wanted to be close to the parking lot since we have a rental car.
i know that 60's is right on the lake and directly in front of the pool and food court. from looking at the map i think building 5 (60's) and building 6 (70's) have what you are looking for. basically right in between the lake and food court and about as close as you can get to the bus stop while still being by the lake. i cant post the link to the map, but if you search "pop map" on these boards you can look for yourself. have a good trip.
