It's important that you choose the right car to maximize your own comfort and enjoyment when driving in the USA. The car size comparisons and suggested capacity are for your guidance only. The number indicated does not necessarily mean that an equivalent number of passengers and pieces of baggage can be accommodated comfortably on a touring holiday. Upgrading your car locally in the USA will cost you more than pre-booking a larger car in the UK. If an infant seat is used, please note that this will take up the space of one full seat in the rear of the vehicle.
