Scopello, Trapani, is west of Palermo, not south (unless there is more than one Scopello). I don’t understand driving an hour East to visit Cefalu just to turn around the next day and drive 2 hours to get back to the airport. The salt farms at Marsala are nice for a short visit. There is the cathedral at Monreale that is very much worth visiting. The cathedral at Cefalu is in the same style, just a smaller version. If you like castles, on the way to Cefalu is Caccamo castle. It’s easy to get to, but there is limited parking. Since you’ll be visiting Agrigento, I won’t suggest Selinunte or Segesta as they are pretty much more of the same. If driving, bring a GPS since the rural roads are poorly marked. I’ll also suggest you look up public parking lots in the towns you plan on visiting and save them to the GPS. That will save you time looking for them. Speed limit signs can sometimes be hard to find, so drive slower than the last one you saw. Of course, beware of the ZTL, no driving zones. They are in every town. While I found them easy to spot, some people don’t, so do a Google search on ZTL signs so you’re familiar with what they look like. I’ll assume you’re not visiting Agrigento as a day trip. It will take a minimum of 3 hours to visit to temples. If you decide to stay in Cefalu, we stayed at Hotel Alberi del Paradiso. It had a very nice included buffet breakfast, and free parking. The road to it is narrow. I looked it up ahead of time so knew what to expect. It also has free shuttle service into the town and back. That worked out well since parking in town in limited. If you decide to spend a night in Agrigento, we stayed at B&B Villa San Marco. It could be hard to find, but we looked it up and knew what to expect, since it’s down a dirt road. The room was nice and breakfast was adequate. It did offer a dinner special to we took advantage of so we didn’t need to drive around at night. From the B&B, we walked to the temples via a path through the olive grove.
