In addition to the improved rocket technology itself, there has been a good amount of residential/business development around what was undeveloped land surrounding Cape Canaveral since the Apollo program ended. So, using a less efficient (1960s design) Saturn V rocket would result in earthquake-like damage to the new communities.

Having said that, if you are anywhere near Cape Canaveral, interested, and even somewhat patriotic, by all means take the tour and see what the US accomplished at the peak of space competition. It will blow you away. I went with my dad, who was only mildly interested, and we both came away with new pride and respect for the sheer magnitude of the project.
