I will be staying in Sorrento next summer for a week. I won't be hiring a car but I will be going to a friend's wedding in Positano one afternoon. Does anyone know how long the bus journey takes from Sorrento to Positano and whether it stops anywhere near Positano Town Hall? Alos, the evening reception is in Conca dei Marini and I will need to get back to Sorrento later that night. Does anyone know how long a taxi ride back will take?
