You can see the main sights in one day, but set aside two days to meander. Romantic horse-drawn carriage rides through the city streets of Oranjestad run $40 for a 30-minute tour; hours of operation are from 7 PM to 11 PM, and carriages depart from the clock tower at the Royal Plaza Mall. Guided tours are your best option if you have only a short time. Aruba's Transfer Tour & Taxi will take you to the main sights on personalized tours that cost $40 per hour. De Palm Tours has a near monopoly on Aruban sightseeing; you can make reservations through its general office or at hotel tour-desk branches. The basic 3½-hour tour hits such highlights of the island. Wear tennis or hiking shoes, and bring a lightweight jacket or wrap, as the air-conditioned bus gets cold.
