Banana Creek/ SaturnV is the closest general public can view launches but the most difficult to get to due to demand.

Reschedules and scrubs are always probable due to weather. Generally the further away from Hurricane season June-December, the less impacts of big weather delays.

Whether at KSC or public viewing, definitely bring: bug spray/wipes, sunblock, foldable chair and water. Public viewing would be the most cost effective but KSC is well worth the admission if you are visiting first time even if it scrubs during day launch.
