I just returned from POP. I completely enjoyed my room 6143. It was in the Mickey Phone building in the 70's. First floor facing the lake and very quiet. My DD3 never was woken up. She loved walking to the rooms because she got to run through the pop jets every night. The playground is also close by. The walk to the busses and Everything POP was less than 5 minutes. I would suggest this building and facing the lake.
I hope you enjoy your trip.
