Help, overwhelmed planning my 65th birthday in April for the Amalfi coast. suggestions please

looking to go to the Amalfi coast middle of April 2025 to celebrate my 65th birthday with my girlfriend. Not sure whether to make our base Amalfi, Positano, or Sorrento. Looking to see each of those towns and I heard a ferry is the best way.

Any suggestions or recommendations? Greatly appreciated. Thank you!
