I don't know how close you need to be to get a good view of a rocket launch. But a couple years ago we camped at
Manatee Hammock Campground near Titusville. There were no launches while we were there, but I have a mental note to try to go back there when there are launches to watch. It is almost directly across the Indian River from Cape Canaveral. You can see the larger structures of the Kennedy Space Center complex from the campground. I think it would be a great place to watch a launch. Not too close; not too far away. I think you'd have a great view of the rocket as it gets farther up in the atmosphere than you would if you were as close as possible to the launch site. Of course, if what you are looking for is the ground-rattling, up-close-and-personal experience, that's something else.
