I've seen a rocket launch at KSC and can highly recommend it. (It wasn't SpaceX though.) One thing to remember though is that launches can easily get scrubbed due to weather, planes flying into the restricted zone etc., so make sure to plan to stay for most if not all of the planned launch window if possible. When I went I stayed at a hotel in Orlando, which can be fun but it's also a bit of a drive so might be worth finding lodging closer to KSC if you're not too keen on driving a fair bit. If you're viewing the launch from KSC your ticket won't be refunded either, and they'll only open up tickets for the next attempt after the launch is scrubbed so you can't prebook for all attempts either. When I went the first attempt was scrubbed, but they launched the next night. This actually worked out better for me, since then I could score tickets to the viewing gantry which was closer to the actual rocket, and an amazing experience. Pro tip: if you're spending multiple days at KSC just buy a year pass – it's worth it. Also pro tip: don't forget to visit the nearby warbird museum as well, they've got an amazing collection of airplanes and very knowledgeable volunteers on staff!
