I've seen it recommended that if making any stops while touring Tuscany by car its better to have a car with a true trunk in lieu of a car with a hatchback (e.g., Volkswagen Golf) if you'll have luggage in the car on those stops (such as stopping in Orvieto en route to Siena from Rome, Lucca en route to CT, etc.).
Is this a rational concern? It seems that the added expense to get into the larger car is roughly US$200.
Thanks in advance for your help!
