Trips from Positano-please help!

We are currently in Positano with 2 days left.

We would like to visit Sorrento, Amalfi, Ravello. We have a rented car and think to do a day trip starting with spending time at Manori or Maiori beach and in the afternoon visiting Amalfi amd Ravello.

The second day, i am not sure if we should drive to Sorrento (that will be a cheaper option ) or take a ferry to see the coast. There is also an option of a tour, i guess. Also, we've been on Capri many years ago and i thought to skip it this time, i would like your opinion if it worh to skip trip to Sorrento and instead to go on tour to Capri.

Thank you very much!
