I will be in Palermo for two and a half days next week, and was interested in spending a day exploring areas outside of Palermo. As I don't want to rent a car, I'd ideally take a day bus tour so I could maximize sites seen, but am having problem finding ones that have January dates. I'm assuming it's because it's off-season? In the absence of an organized tour, what would be the best option to go somewhere like Erice or Agrigento? (I am already planning on going to Monreale on another day.) Or should I go somewhere else, or just spend the time in Palermo? I am open to all suggestions! Thanks in advance!
