IF you can get onto the base, spend the money! We watched one of the night shuttle shots from the the causeway and what a thrill. We also were at the Space Park (with about 100,000 of our friends) to see Musk launch his Tesla and then see the two fuel cells land back on the Cape. These events make one feel pretty small.
Also, if you can, check into a day on the Cape for tours and lunch with the moon rocket. It's been years, but I'm sure they still have attractions to see and do.
We have family in central Florida that we visit (free food and sleeping) so we've been able to see about a dozen launches up close and from a few miles away. Enjoy!!
