Usually Turo isn’t available at an airport so you either have to get to the car or have the car get to you. I think it is a good deal if, like vwlizrd’s son, they can use the same rental over and over, but I’ve heard not good things about the cars not being as advertised, much like a B&B, so now you could be 20 miles from the airport and don’t want that rental.
In the same town I think it would be good.
