Well. They do have lockers, but you should leave the luggage in a vehicle if you can. They go through all bags and scan just like an airport. If you are traveling without a vehicle you may want to ask someone to stash your luggage.
Yes
very small lockers like school. Not big enough for a suitcase. Your car will be safe at KSC, leave ypur luggage in the car. dragging luggage over such a huge huge area from the parking lot to the buildings would be a very very uncomfortable long walk. No real room in bus for luggage, especially on a popular day. The other patrons will hate you if you do something like that that crowds the trip or slows it further for them. NO! Do not try to take luggage to Cape Canaveral. going to KSC with luggage would make for a very bad day. if you try to go to KSC in transit like this between other tourist activities it would likely be quite cumbersome. KSC is not a short tour and doing it with stuff in tow might be very very foolish. If you do not have a house or hotel do not try this. I would recommend seeing KSC but not with other obstacles like luggage or other activities in your day.
The lockers for storage are not very big so leaving large pieces in the car or somewhere else would be advisable.
Agreed
Yes you can store yor belongings in the lockers if you need to.
Yas, the suggestion of Terra Kinder is good one. I agree with her.
