Pop Century is a great resort.
We had mostly stayed at moderates in the past, and were a little apprehensive when we stayed at Pop in June, 2009.
Suffice it to say, the rooms are a little small. But small is a relative term. We had four adults and a baby in the room, and we still could move around without any difficulty. Amenities were sparse, but reasonable. That is, WDW did not pull out all the stops, with Deluxe level bath products, but there was adequate soap and shampoo, and plenty of towels. Mousekeeping and front desk staff were VERY nice and very helpful.
For being a large resort, I can safely say that the food court MOVED people. The only lines were at the checkouts, and those were no more than a 3 -5 minute wait.
The variety of food was incredible. One of our family members has a sensitive stomach, and another is a diabetic. They both left the food court (whether morning, noon or night) completely satisfied. Most appreciated was the fresh fruit and muffins you could buy, in the event you did not want to go the full breakfast route or the high calorie snack route.
The gift shop was well stocked with a lot of merchandise, specific to Pop and also a smattering of things (autograph books, pins, charms, t-shirts, etc.) that you can get at any resort gift shop. Lines were never a problem.
DW is a very honest appraiser of accomodations, and she gave Pop rave reviews. She was a little skeptical at first, before we arrived, but after we checked in, got settled and went to the gift shop and food court, she was hooked. As a matter of fact, she wants to stay there again. Its a great way to get the benefits of staying on property, without the cost of the Deluxe Resorts (which are awesome too).
The only thing I would suggest is to get a preferred area room, so you are closer to the food court and gift shop.
Best of Luck!
