Yep, I have. And I still live nearby.
I like the area a lot, though Cityplaza has gotten more crowded and more commercialised (management has been slowly turning open mall space into pop up stalls, and the central exhibition area is used more and more for image building by single brands).
The podium-level playgrounds are really tiny, and really, really hot in the summertime. Okay to use if you happen to live there already, but not a draw to choosing to live there in the first place.
I just didn't think that Taikoo matches what the OP was looking for in his first post- club facilities, indoor playgrounds. Presumably easy pool access because all kids that age love water. This points more towards smaller developments with clubhouses. Also I believe that his budget is a bit higher than Taikoo. Hence the Grand Promenade recommendation. Though come to think of it, I don't know if there's a pool there- it just seems like the kind of place that would have to have a pool included. Of course, there's also the government LCSD pool next door in Sai Wan Ho, which has a kids' play area with slides and sprinkers in it.
