KidsTowne/Kelly Rd. park, Apex: My kids love this one, they call it Castle Park. I find it's probably the easiest to supervise kids there. Con - No shade at all. That makes it miserable in the pit of summer, but it's our go to from Oct. to May.
Bond has shade but gets very crowded on weekends...BUT...it's the family friendly Triangle. ALL of the parks are crowded on weekends.
Pullen: A fun place to tag team, exhausting on your own with the younger ones. Not our every week play date place, but a nice park to hit every now and then.
Kid's Together: The kids like it. I find I have to keep schlepping from the swingy part to the climby part. Both parts are easily supervisable, if your kids will stay in one part or the other. Mine don't.
