Post cruise suggestions Hawaii

Can you rent a car with pick up at the port, and return to HNL airport. If so, what company will do this?

There have been intermittent reports of Hertz having a desk at the port, but no cars there- you have to be shuttled to the airport. No other companies have been mentioned.

Not any more I don't think.

Where are you staying? If in Waikiki, I'd Uber to Waikiki, then rent from Hertz, Avis or National in Waikiki and return to HNL. If Ko Olina, Alamo and Enterprise for Turtle Bay.
