I am wondering if I must buy a ticket before the Nov 18, 2013 launch or can I just go to the Kennedy Space Center on that day and buy my ticket then? I am an elderly, handicapped, woman and would have to pay $10 for parking, $46 for the tour, and $25 for a handicapped scooter. So I was thinking of driving to the coast/ocean beach at Titusville to see if there might be a place to park near the restroom. If there wasn't space, I thought I would then drive over to the KSC and then buy a ticket. Would this plan work?
