Most of the rentals have the bigger van, but have you considered getting 2 separate cars? When we go with a big group, we always need our "space" after a couple of days. National has such a wonderful deal going on right now, especially with special vacation codes and coupons that you can find on mousesavers.com. If will probably be much cheaper to rent 2 full size cars, then one large van. We always rent 2 vehicles when our adult children come with us because they like to come and go as they please. We rented a minivan once (4 adults, 1 child) and barely got the luggage in. We actually had to fold down the middle seat to pile the luggage on top. If you're a DC member you can get even better discounts on National rental car than the vacation code discounts. I believe the DC is giving 20% off plus there is a coupon.
