Unless there is an event taking place while you visit, there is not much to do at WWoS. We have been there for lunch at AllStar Cafe in the past so my DH could catch a football game. The place was a ghost town.
They use to have something called the NFL experience or Quarterback Challenge but I am not sure it is even there anymore. As for the Richard Petty driving experience - that is not at the WWoS, it is over by the Magic Kingdom.
I think the WWoS is more fun if you are there to see a specific event (which they have alot) but it is quite an amazing complex in general for the sports lover.
