I'd love to visit anywhere in Central or South America, really. But wherever I went, seeing the Pre-Columbian sites would be at the top of my list.

and then be too tongue-tied and only think of all the questions I'd like to ask them afterwards.

This is exactly what's happened to me on the few times that I actually have met a favorite creator; maybe one day I'll actually have the presence of mind to say something mildly intelligent. ☺
