First, thanks to everyone for sharing your insight. Second, the trip to Monreale today (June 6) was a success! Third, I’ll share my transit experience for future reference.
My husband decided to join me and he preferred a taxi option vs. a bus. We’re two days from returning to the US and wanted to minimize COVID exposure and optimize timing.
So … we took a 50-min train at 8:43 to Palermo Central Station, which was air conditioned, quiet and scenic. Cost: Euro 12 pp round trip. Then, we found a driver at the official taxi stand and negotiated a fixed fare (using my elementary Italian) for the 6-mile, uphill trip on a tiny road. Cost Euro 40 one-way. We gave him a 50 and he claimed not to have change. Then, after our gentle prodding, he gave in and we got our 10 Euro change. Our driver was a little older man with missing teeth and bleary eyes, but he guided us up the steep road expertly.
We were lucky to visit the amazing cathedral and cloisters for two hours at 10:00 before any big crowds and had a yummy lunch on the piazza afterwards. The restaurant called a taxi for us. This taxi, a comfy van, returned us to Palermo for Euro 30 (his offer). I spent a couple hours enjoying the sights, smells and sound of walking Palermo’s neighborhoods before returning to Cefalu.
Yes, the taxi was a pricey option but it worked for us. Cheers.
