The main catch at San Juan Airport is that all 4 desks take credit cards only, refusing debit cards for the vehicle deposit. Arriving without a credit card in the primary driver's name means walking away without a vehicle. Large SUVs will also penalise you in tight historic areas where street spots are rare and garages are narrow. A smaller car handles local traffic and tight turns far more easily.

Fuel is full tank out, full tank back on 100% of prices at San Juan Airport, so there is no fuel charge to be surprised by.

An Intermediate car like the Toyota Corolla costs $81 a day at San Juan Airport for October 2026. An Intermediate seats 5 and holds 4 bags. Stepping down to a Compact car like the Nissan Versa carries 5 passengers but only 2 bags, so a full car leaves luggage behind.
