While I will always love DQ, I was there a few weeks ago and it looked rough. Several things were closed and some empty spots were noticeable. If you want to go back for nostalgic purposes, that would be good, but it is not what it was. Of course a 6 year old may like it, but to me, I would think you would get more time at a water park. I can't see spending more than 4 hours at DQ and that would be a long time.
