We will be staying in Sorrento for 3 nights next week and would like to take a day trip to Positano. We got a recommendation to see Chef Andrea at Buca do Bacci and I noticed they have a cooking class followed by dinner which sounds fun but I think we will finish too late to catch the ferry back to Sorrento. I would like recommendations on the best way to get back from Positano to Sorrento in the evening. What are the options and estimated costs? Thanks!
