You can look at the map on the Resort Forum under each resort - they are usually on the first page. If you are in LK section, building 6 is closest to the bridge, and for POP the 60s buildings are closest. You could request these to be close to each other over the bridge, but then you would not necessarily be close to the front where the buses come and food court are in your own resort. For that LK building 10 would be closest, and at POP 6o's is still good, but closer rooms will mostly be preferred. I don't think there'd be a big difference where you leave from, one will have to walk across the bridge and to the front of the other resort. We have only stayed at POP, but were happy with the service. Coming back to the resort at night, you could take whichever bus is there first, or take seperate buses back for less walking at night( if you both stay near the front).
