In January 2011 I reserved an Economy class car (Nissan Sentra 4dr or similar) through Expedia for pick up at the San Jose airport for our February 2011 trip to Costa Rica. However, upon arriving at Dollar I was informed that they did not have Nissan Sentras for rent. Their only Economy class car was a Suzuki Alto, which is substantially smaller than a Nissan Sentra. Since we needed a larger vehicle for 4 adults and 4 suitcases I had to upgrade to a Suzuki Grand Vitara on the spot, which more than doubled the cost of our car rental. Upon returning home I checked Dollar's website and it only shows Suzxuki Altos as their Economy class car while Expedia shows Nissan Sentras as Dollar's Economy class car.
After resolving this issue we enjoyed our 16 day trip.
