Update to Post:
We have settled on renting two small cars from McCurley. Present understanding is the two cars were about the same price as an 8 passenger van, so opted for the flexibility of 2 vehicles.
The nice thing about working this out with McCurley appears to be that 1 car will be at house waiting for us, the other will be at the airport. Some of group with all the luggage will go with McCurley shuttle to house, while a few of us go off shopping.
So far sounds very accomodating.
More later.
