💰 Budget
🛡️ Safety
Aruba
Aruba is among the safest destinations in the Caribbean for tourists. Violent crime is rare; petty theft (unattended belongings on the beach, hotel-room incidents) is the most common issue. The island's tourism economy depends on its safety reputation and the local government, police, and tourism authorities work hard to maintain it. Walking around Palm Beach, Eagle Beach, and Oranjestad is comfortable day and night.
Saint Lucia
St. Lucia is a safe tourist destination in resort and tourist areas. Petty theft occurs on beaches. Castries and some areas of Gros Islet require awareness. The tourist infrastructure is generally well-managed.
🌤️ Weather
Aruba
Aruba has the most consistent weather of any Caribbean destination — average highs sit between 28°C and 32°C every month of the year; lows rarely drop below 24°C. The island is technically OUTSIDE the Atlantic hurricane belt (12°N is the latitude where most hurricanes form, and Aruba sits at 12.5°N — but practical hurricane-strike risk is minimal). Constant 15-25 mph trade winds from the northeast keep the island feeling cooler than the temperatures suggest. Annual rainfall is just 470 mm — among the driest in the Caribbean.
Saint Lucia
Tropical climate. The dry season (January–April) is the most popular. The wet season (June–November) includes hurricane risk (peak August–October) but also lush green landscapes and good diving visibility.
🚇 Getting Around
Aruba
Aruba's transport options are taxis (no Uber on the island), the Arubus public bus system (cheap, scheduled), rental cars (drive on the RIGHT, Dutch tradition), and walking around Oranjestad and the hotel strips. The Arubus Line 1 runs the full length of the western coast from Oranjestad through Eagle Beach to Palm Beach every 15-30 minutes — useful, cheap, and direct.
Walkability: Walking is good within Oranjestad downtown and along the Palm Beach pedestrian strip. Between districts requires bus, taxi, or rental car. The trade winds and shade make daytime walking pleasant despite the temperatures.
Saint Lucia
The island has no public rail. Taxis are fixed-rate from the tourist board. Minibuses are cheap but basic. Water taxis are the scenic way to travel between coastal points.
Walkability: Limited walkability outside resort areas; most attractions require transport; Soufrière village itself is walkable
