This campground has a split personality. The west side has nice wide concrete sites, the east side is on dirt and gravel and not so nice. When I made my reservation I missed the pick your site($30 add on?), but given the difference between the two sides, it would have been worth it. This is definitely a KOA Journey, hookups work, good for a night or two, but not a destination. I didn't think it is quite as close to the Space Center as described.
Some long term residents, many on the east side, and the roads aren't very wide. The gentleman who escorted us to our site took us off the road and out into the grass to get around a tree to make the turn workable. Most of the staff was friendly and helpful.
Oh, if you look at this campground on Google's satellite view, be aware that there is a different campground that wraps the KOA on the west, and south. If you see tennis courts, you're looking at the wrong campground.
Given the history of this area I had high expectations. If you get one of the nice new sites, then I think it's worthwhile, otherwise this is one of the few KOAs that I don't think I will recommend for more than a night maybe two.
