If you are at Orlando to visit Universal Studios do make it a point to visit KSC. It's an hour drive from Orlando. Be prepared with change for toll. There's a few. We spent 1/2 a day and were able to cover all the basics. Start with the tour. I think the first one departs at 10am. Make sure you experience the Space craft stimulator and the best one of all visit Atlantis. That was the highlight of our visit. Kids will enjoy touching the moonstone.
