Kennedy Space Center Visitor Complex
Some of humankind’s greatest adventures began here at NASA’s launch headquarters, an easy hour east of Orlando on the Atlantic coast. Time your visit right, and you may see a space shuttle streak into the sky on liftoff (visible all around the state but much better from up close). Attractions include Q&A’s with astronauts, plain-speaking technical explanations, and a launch-simulation ride.
Tip: Getting around the center requires taking on-site buses, and the last one sets out around the property between 2 and 3 p.m. Arrive early in the morning to give yourself plenty of time.
