What's your favorite Kennedy Space Center Tour?

I want to go on another tour at the Kennedy Space Center. There is so much cool stuff going on there! The best tour so far has been the "Then and Now" tour, where you go to Gemini and Mercury, and see the old bunkers, computers, and gantry, and then Apollo, then see the Falcon 9 pad from afar. And of course end up at the old Saturn V museum building. There's so many interesting things out there. If you haven't been, it is worth the trip. If you have been, What's the best tour you've been on?
