I stayed at Pop two years ago in September. It was great! I was in the 70's building closest to the main hall. It was a 5 minute walk to the food court and the bus stops. Any of the 50's, 60's or 70's buildings are pefect. I would definitely stay there again.
Buses: Catching a bus at Pop in the mornings wasn't bad. I always tried to get to the park early so the line was almost non-existant and the wait was short. As a PP said, the bus stops at the parks are the furthest away, so be aware of that. It's not a mile hike, but it isn't right next to the enterence either. Overall, the bus situation for Pop is very reasonable.
Leaving MK for the night was a little crazy! Usually the line fills the corral and some extra. Usually though, Pop would start loading one bus, another bus would pull up beside it and start loading...all the while a 3rd bus was pulling around the horseshoe. So you weren't waiting on line very long. I found it best to wait a bit after the fireworks end (30-40min) before I started
heading out of the park. It helped to alleviate that get-outta-the-park-quick mad-dash to the bus stop junk.
Food: The food court has pretty good food. I always found something to eat. I got to the food court shortly after it opened and it was always empty. I ate dinner there once or twice at an off time and tables were available. I don't know what it's like at a peak meal time but I can guess it's very crowded. But hey, if you time it right, they do the twist for you in the morning, and the hustle in the evening!
This story is not to scare anyone, but it was a site! One night leaving MK, the line for Pop was horrendous! When just turned the corner around the information booth (the far side of bus stops) and we saw the end of a line, but we assumed it was for another resort. We followed the walkway down towards Pop and soon realized Holy Moly that line is for us!!

After we picked our jaws up off the floor

, we parked it on a bench near the Pop bus stop and just waited it out. In about 10 minutes the line was small enough to fit into the corral. We hopped on, waited a few and a bus pulled up. We realise that we didn't wait inside MK very long after Wishes. That night was the only problem we had with Pop buses.
