I am still trying to talk my wife into making the trip, my son is 8 years old and loves the Tesla. He is very excited about going on the Factory tour. 54 inches tall so I think he is okay for that. If my wife doesn't go I would still like to take my son with me and still go to a few of the sessions. He's very smart for is age and even does is own programing in Minecraft. He watches tech tutorials on computers and videos every day just for fun. If it's is okay is there a half day pass for Saturday and would I need to buy two tickets?
