We have gone to KSC on launch day and it's a parking lot. The road that goes by the Astronaut Hall of Fame doesn't move. Also, you can probably see the launch better from Titusville. The trajectory takes the shuttle north and away from the Space Center. The Hall of Fame isn't far out of the KSC gates. You should have a clear view from across the river in Titusville.
We'll be in Daytona and hope it's clear that morning so we can see something also. Don't feel like fighting the traffic to get closer.
Hope you all have a fun time.
