Orlando is a place for everyone to enjoy. From Disney to Universal, from Nasa to the Keys, Disney is truly magical for both young and old. There's not one boring moment from start to finish.
As an adult myself, I have to say that I preferred Universal Studios and Islands of Adventure. There's so much to do and the rides are thrilling.
If you can, take the short drive to NASA where you will see the various rockets that have been used throughout the years. There's also plenty of info on the space shuttle and space exploration.
