Will be in CR next month. We arrive after dark and have reservations at the Hampton Inn near airport.
It's been 5 yrs since our last visit, but I recall there were a handful of car rental agencies across the street from Hampton. In addition, there was an Avanti location down a hidden driveway behind the hotel.
Is it still the same?
Can you avoid the airport tax on car rentals by renting direct from office(s) located near the hotel?
