Aruba is a small and beautiful island, 20 miles long by 6 miles wide but with many points of interest, beaches and restaurants to visit and enjoy so if you are planning to go around the best and cheapest way is with a rental car otherwise if you want to relax at the beach/pool you won't need it as some guest said once " a car is convenient but not a necessity " , the best and biggest supermarket is just 1/2 mile away walking distance so you can walk over there and take a taxi back with groceries, about $8 ride, airport- property ride is about $28 max. 5 persons, downtown-property ride about $12-15, palm beach-property about $10, walking distance there are very good restaurants like "Chalet Suisse", Passions on the Beach, Screaming Eagle.
