Myself, DH,and 2 DD's stayed there in October of last year. We really liked it. It only took us about 10 minutes to get to Disney and there was never any traffic, all back roads.
As far as kid friendly, there was a playground at the Vistana Villages and a nice pool with zero depth entry at one end. The kiddie area of the pool was quite large.
We spent all day at Disney and used the pool at night so I can't tell too much more about the resort. We did really like our room though. We had a two bedroom unit and it was beautiful and really spacious.
