We've stayed at Pop a few times. Our favorite (by far) room location was lake view, 4th floor, building 4. We could see fireworks from our room every night, we were steps from the main pool, and the food court and bus stops were a quick walk. And the bonus was that even though we were super close to the pool, since we weren't facing the pool, we didn't have any of that noise. We were there before AoA opened so this wasn't a benefit for us, but that room location is close to the bridge to AoA which makes it easy to walk over there to eat in their food court and also gives you the option of taking the bus back to AoA from a park if that line is shorter than Pop's. And it's also close to the Skyliner station (which will be open/running by the time you go).
