We just rented 2 full size cars from National for 10 days-Emerald Aisle. My husband has a membership and so do I (see Mousesavers for free card info). So each of us rented one. They were $190 ea. including taxes for 10 days. There were 6 adults & 1 infant in a car seat. Plenty of room for people, but crowded on luggage space. If I could just talk my daughter into not taking everything! HA! But with husband's golf clubs, full size stroller & 7 bags, we made it. Last yr with 5 adults and 1 infant we had a full size van and still had the same luggage problem. This time we were able to use 1 car's back seat to transport extra luggage & put 4 adults & baby in the other. It worked well and was about the same price as the van.
