We split our stay in July at Pop Century and Wilderness Lodge. We loved our stay at Pop Century!!! We booked 60s too (DH & older DD love the 60s).
Anyway, we were in the bldg with Mowgli & Baloo - Room 5312 (third floor at the end of the hall). We were overlooking the kiddy pool area.
Our room was very quiet - we never heard our neighbors or any noise from the pool! And it was a short walk to the food court/bus stop!!
Enjoy your stay!!!
