We loved Pop. We stayed there this past September. The theming is fantastic. We didn't take transportation, we rented a car, so i can't speak for the bus system. The food court was great, and the pools were clean and not overcrowded. Mousekeeping was wonderful, we needed extra pillows and towels, and they were there within ten minutes and remembered to leave extra towels for the rest of our stay. The rooms were clean.
We liked it so much, we booked a bounce back program trip for this coming september!
Now, this is coming from someone who is spoiled and gets to spend every other trip staying on my parent's DVC points at one of the bigger, two bedroom hotels. Granted, they are wonderful, but I wouldn't pay the money to stay there.
