I told the gentleman at Dollar Car Rental that we were going 'old school' in response to his question about whether we would need the GPS for $84 per week. That expression seemed to translate well in Costa Rica. He gave us a map and a wary look while his teammate nodded approvingly.
I had been warned about the upsell at car rental agencies in Costa Rica, but this fellow was a really great salesman. Apparently with the level of insurance that we purchased, we can return a smoking hulk of a car resembling the one from Planes, Trains and Automobiles and it will not cost us another penny.
