We went to the Kennedy Space Center the day after Labor Day and it was Empty! We took advantage of this and took tons of pictures.
Hint: I was tempted to purchase KSC tickets online but we waited and stopped at the Florida visitor center where they had $2.50 off coupons. Bonus. KSC tickets are good for two days within a seven-day period.We also took advantage of free admission, part of our KSC admission, to the Astronaut Hall of Fame. It is a wonderful, small museum. The exhibits are interesting and there are many hands on opportunities
