Traveling to Sicily, but only have time for one day in Palermo. Plan on taking train from Santa Flavia into Palermo. What are top things to see and do in Palermo?
Here is a list to pick from:

You won't have time for a top ten, I suggest you pick three. Is Monreale something you want to see that day?
What's your plan? You posted that you plan to drive from Santa Flavia to Monreale. Is that on a different day?
The two things that most stand out in my memory are the Old Palermo self-guided walking tour, copied from Frommer's website, especially San Giovanni degli Eremiti and the Palatine Chapel, and the Ballaro market.
