Tips for renting a car in Boston

• Book early — rates for Boston climb as availability tightens near your dates.
• Compare the total price, not the daily rate: fees, insurance and mileage add up.
• Prefer suppliers offering free cancellation so you can rebook if the price drops.
• Picking up at BOS airport is usually the widest selection, though city-centre depots can be cheaper.
