You can learn a lot about scientific advances from taking a tour of a medical institution. Check to see if Nemours Childrens Hospital is open to visitors while you're in town.
This health care institution is free to explore, so you can have a fun day out without ever opening your wallet. However, Nemours Childrens Hospital isn't the only place to visit in and around the commercial neighborhood of Lake Nona Medical City. With Austin-Tindall Regional Park, North Shore Golf Club and Eagle Creek Golf Club not far away, you may be tempted to stay a little longer.
