We want a single base between Palermo and Trapani for 7-10 days, with day trips in the area. The home base could be either of those cities or a town in between. We'll have a car and if staying in Palermo would only use the car if travelling outside of the city for day trips. Does it make sense to stay in Palermo, or would it be easier to stay in another town to do day trips in that area including trips a couple of days Palermo?
