We live just a couple of hours north, and find it worth it to have yearly passes. More specifically, one yearly pass, which comes with free parking, and the other three of us get unlimited admission for the year, but not free parking.
It's really worth seeing. My family isn't really interested in the theme parks here in central FL, but love KSC.
I'll focus on one aspect of our visit this week. At the Mission Control center, where they display a Saturn 5 rocket, we talked to a retired flight engineer that had been in launch control for the entire shuttle program. He explained that the Saturn 5 that is on display was sent to KSC to be used. He also told us how each of the three stages were manufactured by different companies, and shipped to Louisiana where the were tested with a "full duration practice burn", before being shipped to Florida.
I'd seen this Saturn 5 previously, but knowing that it had been lit, and had the engines burn long enough to reach orbit really changed my perception of this incredible machine. For context, the largest and most powerful rocket right now is the Falcon Heavy. The Falcon heavy is basically three Falcon 9 rockets attached together, yet the Falcon heavy is smaller and less powerful than a Saturn 5.
They also have the lunar landing module that was built for the Apollo 15 mission. When Apollo 15 was designated for the first use of the lunar rover, they had to redesign the landing module to fit the rover, so it wasn't used. It's hanging in the same building as the Saturn 5, and once again, it's NOT A MOCKUP! It's the real thing!
There's much more to see there, we've been multiple times and still haven't seen it all. Don't miss it if you have the opportunity to get there.
Here's a picture of the bottom of the first stage, and no, it's not distorted by the photo. This thing is enormous! The largest and most powerful machine ever built!
