I have stayed at both. We stayed at All Star Movies in 2002 with my entire family - there were 12 of us in all. My son was 2 at the time. Everyone loved it and we had a great time. My son loved all the big Icons he knew from the Movies. In 2004 my DH, DS (5) and DD(2) and myself stayed at POP Century. We also loved it there. (As long as there is a pool my kids are pretty happy anywhere). Personally, I liked POP better. Maybe because it was newer but we really liked the pools, food court and all the icons. The buses only stop there where at the ASMO they stop at all the All Star Resorts. I don't think you can go wrong at either place.
