Can I leave the airport on a layover in Aruba?

Five hours is the floor for leaving Queen Beatrix International Airport. Immigration runs 10-20 minutes inbound. It can stretch to 30 when the Miami and Newark flights cluster within the same arrival window. A taxi to central Oranjestad costs $10 USD (about 18 AWG) and takes 7 minutes on L.G. Smith Boulevard, the coastal road connecting the airport to the downtown waterfront. Budget 90 minutes before your departure for the return trip and security. That math gives you roughly 2 hours in Oranjestad on a tight connection. Anything shorter, the terminal has a few food counters, free Wi-Fi, and air conditioning cranked low enough that you might want a layer. There is no transit hotel or sleep pod at AUA.

Oranjestad is a compact town you can cover on foot in 45 minutes. The pedestrian stretch along Caya G.F. Betico Croes runs about 6 blocks with enough shade from overhanging second-story balconies to make the heat manageable. The trade wind is constant, 15-20 km/h most afternoons, and you'll feel it the second you step out of the taxi. For a solo lunch, the bar seats at waterfront spots along the Renaissance Marketplace work well. Nobody blinks at a single diner. Order keshi yena, Aruba's national dish, a baked Gouda shell filled with seasoned chicken. It tastes richer than it sounds, salty and dense with a slight sweetness from raisins and olives. Fort Zoutman, one of the island's oldest structures, sits 2 blocks inland and takes about 15 minutes to walk through. Aruba scores 7.8 out of 10 on TTDI's solo-traveler safety scale (see the TTDI Solo-Safety Index), and Oranjestad in daylight feels low-risk by any standard.

With 8 hours or more, push north. Eagle Beach is 10 minutes from the airport by taxi ($12-15 USD) and has the famous divi-divi trees bent permanently sideways by the trade wind. The sand is white and fine, almost powdery, and the water temperature stays around 28°C year-round. Solo travelers can rent a palapa for $10-15 and settle in without needing a resort wristband. Palm Beach, another 5 minutes north, has more bars and foot traffic if you want company. A Balashi beer at one of the beach shacks runs about $5. Mind you, Baby Beach at the island's far southern tip is 30 minutes from AUA, so it only fits a layover of 9 hours or more. The shallow lagoon there barely reaches your waist 50 meters out.

Taxis are the only realistic transit for a layover. Arubus line 10 connects the airport area to Oranjestad, but headways stretch to 30-45 minutes and no printed schedule survives contact with the actual departure times. Fares are fixed by zone and posted on a board at the airport taxi stand, so there is no meter negotiation to manage as a solo traveler. US dollars work everywhere along the tourist strip at roughly the posted 1.79 AWG rate. English is widely spoken alongside Papiamento and Dutch, so a phrasebook is optional. That said, if you want to attempt Papiamento, "Bon dia" (good morning) and "Danki" (thank you) go a long way. Oranjestad's waterfront stays well-lit and calm after sunset, though the blocks south of the pedestrian street get quieter. I'd walk the main strip alone at night. The return taxi from town is easy to hail on the main waterfront road, but from Eagle Beach you may need to ask your beach bar to call one. Build in 15 extra minutes for the pickup.
