We are staying in Positano and would like to spend the day in Capri. We would like to leave Positano early and find a "giro" tour around Capri, see Capri & Anacapri. Then take the last ferry back to Positano. Is this feasible? If so, please let me know which ferries and if you have any suggestions for boat tour companies. We do not have to have a private tour. Thank you for your help!!!
