Your Mar del Plata Adventure Starts with a Car Rental from MDQ

You'll need an International Driving Permit (IDP) alongside your US license. Argentine rental companies require the IDP as an official translation—your US license alone isn't sufficient. Get one from AAA before departure ($20-$30). Without both documents, the rental agency will refuse to hand over the keys, no exceptions.

Toll booths (peajes) accept cash (pesos or USD) and some credit cards, but electronic tags like TelePASE save you from hunting for exact change. If you're driving from Buenos Aires to Mar Del Plata (400km round trip), you'll pay roughly 2-3 tolls each way totaling around $5-8 USD. Renting a tag device costs about $5/day—only worth it if you're doing significant highway driving beyond this trip.

Expect to pay a "young driver" surcharge of around $15-25 USD per day if you're under 25. At 22, you'll definitely hit this fee. Some agencies cap it at 21+ but most charge until 25. Budget an extra $150-250 for a typical week-long rental. This fee is non-negotiable and often isn't included in initial quote comparisons.

Argentina uses unleaded gasoline (nafta sin plomo 95/98). Gas stations are plentiful along major routes like the RN2 highway to Mar Del Plata, but can be sparse in rural areas. Fill up before leaving major cities. Most stations accept credit cards—cash (pesos) is recommended for remote areas. Prices run roughly $1.20-1.50 USD per liter, so a full tank for a compact sedan costs around $40-50.

Street parking in the central beach district costs $2-5 USD/hour during peak season (December-March), with meters operating 9am-9pm. Side streets near the harbor are cheaper or free but fill by 10am in summer. Major malls like Shopping Mariso offer affordable parking (~$3/hour). Avoid parking on Avenida Marine—towing is aggressive and a nightmare to resolve.

Summer (December-February) brings heavy beach traffic on the RN2 highway—weekends see 2-3 hour delays departing Buenos Aires. Winter (June-August) brings foggy mornings reducing visibility to under 100 meters on coastal stretches. Rain is common year-round and makes coastal roads slippery. Summer thunderstorms can flood low-lying areas near the beach. Check your route on Occerp (Argentina's road authority) before driving during extreme weather.
