Parking regulations
You need to consider carefully where you park as theft from and of parked cars is rife in Costa Rica. Keep all valuables hidden or, better stll, don't take them with you when you leave the hotel.
Paid parking
Choose bona fide parking areas or garages wherever possible. Use ones with CCTV if possible too. Even some of the attended lots can have problems with the attendant advising car thieves of new arrivals. Be wary if the attendant asks how long you will leave the car.
Enforcement
Parking laws are rarely enforced leading to haphazard parking in towns and cities.
Disabled parking
Costa Rica has no regard for European disability regulations but if you take your card with you and show the garage attendant, most will try to get you a more convenient space in exchange for a tip.
