Taxis are lined up just outside the arrivals hall to the left, and they're one of the easiest and most reliable ways to get from the airport to your hotel. Some taxis have meters, but most don't—Aruba uses a fixed-fare system based on destination zones, which are set by the Department of Public Traffic. Always confirm the price with your driver before you get in, and don't be surprised if it's quoted in both US dollars and Aruban florins (the exchange rate is pegged at AWG 1.80 to $1.00 USD).
You can also book taxis in advance, and some drivers will meet you right at the arrivals hall with a sign displaying your name—this is especially helpful if you're arriving late at night or traveling with a lot of luggage. Airport taxi rates are government-regulated, so you won't need to haggle. As examples: a ride to downtown Oranjestad costs about $21 USD during the day ($24 at night), to the low-rise hotels around Eagle Beach it's roughly $26-28 USD, and to the high-rise hotels in Palm Beach it's around $30-31 USD. These prices are per taxi (not per person) and can accommodate up to five passengers, with kids under age two not counted toward the passenger limit.
There's a $3 USD surcharge on Sundays, official holidays, and between 11:00 PM and 7:00 AM. Also, each passenger gets one piece of luggage included, but additional bags cost $2 USD each. Taxis in Aruba are cash-only (US dollars or florins), so have small bills ready—drivers may not always have change for large notes. Tipping isn't required but rounding up or adding 10-15% for great service is always appreciated.
