There's no mention in any of my books about batting cages at the Sports Complex, debe. In fact, other than the Richard Petty Driving Experience and the NFL Experience, this seems to be mostly for spectators.
Maybe he'd like to do the Rock Climbing at Blizzard Beach?

No, there aren't any public batting cages. Lots of wonderful fields and facilities to drool over, but no opportunities to play ball. However, the NFL Experience is at least as good as batting cages, if football can be considered a fair substitute, and that experience is included in the price of admission.
Wide World of Sports does play host to independently-operated sports clinics. Ya never know, there might be something of interest to a softball coach during your visit. They used to list a schedule of all these things at their Web site, but I can't find it now. You may have to phone.
