I just got back from a stay at POP myself and enjoyed it immensely!!! And yes, I was another guest assigned to the 50s building! I was a bit disappointed at first since I asked the CM at the front desk for availability in the 70s building, but having a room in the 50s building ready when I checked in at 7:15am(!) more than made up for it. I was expecting to have to leave my bags with luggage assistance, instead I was able to go to my room, unpack, get refreshed, and manage to get to AK for EMH.
Unlike nowellsl, my room was in building B of the 50s, in the wing FURTHEST AWAY from the Classic Hall and Food Court. There are 3 buildings that make up the 50s, and bldg B is at a location disadvantage to the Classic Hall. The walk/distance isn't too bad, but I did feel jealous at all the other 50s guests who were a lot closer to the Food Court than I was.
cathie, for the 50s section, buildings A & B are closest to the parking lots. However, another thread about POP parking mentions that the handicap spaces were usually occupied. You may want to prepare for the possibility of having to drop your friend off at the curb and have someone park the van in a non-handicap space. I think Tyler mentioned that there are further plans to improve the parking, but it may take some time.
Overall, I really enjoyed POP. It was a fun place to stay and it was nice to stay in someplace NEW. The food court was usually busy, but the lines moved quickly. And unlike others, I LOVED the brand new fluffy pillows. Ahhhh...they helped me sleep very well indeed!
