We will neve rgo without a car for th eentire trip again… but if we were looking for just one day of renting to get groceries, I would just go ahead and pay the delivery fee, because I can’t imagine it would be more than a rental car.
You could get a cheap taxi and head over to Goodings very easily. It’s so close and it also has liquor, so no second stop at a wine shop.
We have had groceries delivered (ther eare two services, I believe, that you can choose from) every trip since we discovered the service. Love it!
