we stayed at manatee hammock a few years back when we were in the popup. It was a great place from which to watch the shuttle launches.
The park wasn't anything special and nothing fancy but certainly ok, and I don't recall anything re large/longer rigs... just wasn't looking for that then. I do remember it being shaded with trees.
I remember Railroad tracks nearby, not rattle your teeth close, but you could hear it.
Oh, and the fire pit rental. No fire pits, you could use your own pit if you had one, or rent one from them. I rented one and laughed out loud when they delivered an old perforated washing machine tub and a couple cinder blocks to set it on!
