Take my advice, book your car early and choose the largest size available if possible! Don't make the mistake I did—five people squeezing into a full-size SUV. After loading the luggage, it still felt cramped, and some of us are on the heavier side. I ended up paying extra to upgrade to a minivan. The staff member at pickup was very helpful, and the upgrade cost was reasonable within company policy. They provided us with a brand-new limited edition vehicle with only 200 miles on it. Luckily, we switched cars—my travel companions were very satisfied with the rest of the trip.
