I'm with the cheapest option. 2 Adults, 1 child and 3-4 bags could fit in an economy car. The bags will only be with you to & from the resort. Put 2 in the trunk, maybe 3 and the rest in the back seat. This of course assumes you are flying in and renting and no one is football or basketball player sized!!! My co-worker calls me creatively frugal so I would never book anything larger than absolutely necessary.
