We loved Pop when we stayed there this summer. Our FAVORITE part was the Frozen Cokes for the unlimited mugs! No other resort has these, and my d and I made great use of this! They also had games by the pool for the kids during the day, and at dinner they danced in the food court. They also have this walkway with signs telling about the different years.
Oh, my every day my girls went out front and drew on the sidewalk with the chalk at the entrance. They loved this (and my kids are in middle school...but they still loved all of this).
If you are staying at All Stars, we have only been at the movies and music, and my kids liked the movies better, but you can walk around to all of them, so which ever one you stay at you can still see the theming of the others if you like.
We probably wouldn't stay at All Stars again, we love Pop for the values (we stayed by the big Mickey Phone).
