Overall, this was an OK place to stay during my vacation to Disney World. I thought of it as the "Motel 6" of all the Disney Resorts. The room was clean and neat. I had to call maintenance the first night to unclog my bathroom sink because it was not draining. They had it fixed the following day. The finishes (carpet, bathroom fixtures, etc.) were really outdated and needed replacement badly.
The worst part of Disney's Pop Century Resort was the food court. I would consider it more like an elementary school cafeteria - the quality of the food was terrible. I tried everything from the eggs to the hamburgers to the donuts, etc. All of it was nasty, tasteless crap. Oh, and, of course, WAY OVERPRICED!! I could have cooked a better breakfast myself (and that ain't sayin' much).
DO NOT waste your money and buy the "souvenir mug" IF you don't plan on spending a lot of time at the resort. This mug is only refillable at the resort itself, SO if you plan on spending most of the time within the Disney theme parks then DON'T BOTHER BUYING THE MUG.
One last suggestion, if you plan on checking in for your flight at the luggage check-in for the Disney Magical Express plan on this taking AT LEAST an hour. The desk was short staffed and the employees took their sweet time checking in bags.
