Car Hire- Collect Ibiza Airport return near Formentera ferry

Hello,

We need to collect a rental car (Large 7 seater) from a car rental company based inside Ibiza airport terminal that we can return at the Port- ideally as close as possible to the Formentera ferries.

I can see a few based around the port but not sure which ones are closest to where the Formentera ferries leave from.

We will have my elderly parents and 2 children so we are looking for the easiest and closest options.

Any suggestions greatly appreciated!
