I have heard that that buses even in the early morning hours from Sorrento to Positano are very crowded now. I will be in Sorrento on July 26 and was hoping to take an early bus to Positano. Am I dreaming?
There is one early bus at 6:30 AM, then starting at 8:30 there is a bus every 15-60 minutes until the last departure at 11:00 PM. You heard right - in July virtually every bus will be crowded, especially the early ones. Here is a link to the schedule: http://www.sitabus.it/sitabus/campania/orarioCAMPANIA/QUADROXV.pdf
Is it true that there are no organized lines and everyone just makes a mad dash to get on the bus?
No organized line, yes.
Mad dash, sometime.
the bus leaving sorrento is a mad dash in the morning. if you want orderly boarding, use a boat instead, and take the bus back.
