Yikes.
Yes I like that as per my suggestion that you decided upon one of the Amalfi Coast or the Cinque Terra, but with the former I see you are going for Sorrento.
Let me suggest Positano, Positano, Positano instead!
Why? Well my wife and I had a pleasant night and day at Sorrento, but that is all you need when there are better options to be had. And if you miss it entirely, no loss. Whereas Positano is the stuff that creates lifelong travel memories.
The pic my below is of my wife looking down at the "beach" in Sorrento.
and here is the close up..
Whereas this is us the small beach nearest us as we stayed a 15 minute walk south of Positano
Which was a little less crowded and more relaxed than the main beaches of Positano, but which was still way better than Sorrento.
Positano has a great ambience at night. Whereas Sorrento is more big city rather village feel.
The view from our private garden terrace outside of our B&B room...
And go on a small boat trip to Capri, or the main ferry to Amalfi and have no traffic hassle at all. The shot below is over the stern of the small boat we shared with 6 other people to Capri.
The private limo we booked from Sorrento to Posiatano was not expensive and the drive and time were not that horrendous. Ditto for the limo from Positano to Naples Train Station to catch a train to Rome where the trip was longer due the distance but timewise not that long compared to other options..
I know that some paint a horrific picture of the Amalfi Road Traffic, BUT you can avoid it mostly by simply minimising how much you are in it.
The limo from Sorrento to Positano each way was only an hour at most.
Take the ferry from Positano to Amalfi = no traffic
Hire a boat or a small boat cruise for other trips = no traffic.
Also at night the traffic drops to very little and so if desired you can arrived or depart late (personally I would not bother).
To do the Path Of The Gods we actually caught the local bus from Amalfi to Bomerano (Taxi prices were horrific) and it was not that bad a trip and we were there in August.
