The next day we drove out to Kennedy Space Center and explored around there most of the day. Very cool place. I particularly enjoyed the Apollo/Saturn V center. It's hard to imagine just how large the Saturn V really is until you see it up close.
Our last full day we spent the evening at Downtown Disney and saw Cirque du Soleil's La Nouba. I love Cirque du Soleil. They're so much fun to watch. And like many shows, it's even better to see in live. Definitely worth going to if you have a chance.
